It's most important that you both want to go for your marriage. As in really go for it, because it'll take a lot of time and commitment. This includes that your husband realizes the consequences of this choice, it's having the cake or eating it, but not both.

How did you get past the initial phase of accepting your spouse's orientation? How did you trust again? When did you stop crying??? What has been the key to your success. I need some positive here.

Acceptance is more than acknowledging the fact of your husbands sexual orientation, it is the first (necessary) step. And it's important to face it as it is, not denying or downplaying it.
Complete acceptance has to evolve, because as long as his sexual orientation causes you to feel hurt (rejected), it's not really possible to fully accept it. 
Rebuilding trust is no different. Through talking, honesty and openness, trust can and will eventually be restored. There is no magical method for it, it happens in the background.

All depends on the personality of you both, what love is about, and the way you make choices in life. In our experience the sexual orientation on itself is of less importance. 
For instance if your husband thinks fulfilling his sexual wants is more important than you, it won't work out. That's no rocket science. But the consequence is also that his choices and decisions are aimed at you and your relation together. 
That should be his priority, not his sexual orientation. This is not about suppressing or denial, rather giving it the place where it belongs: It's a part of himself, but not his "all defining identity" as contemporary culture tries to convey.

I suspect his sexual orientation was a central item in his thoughts for years. Keeping it hid from you for that long was not a wise thing to do, because I think it grows in perceived importance that way. And creates problems in the sexual relation that could be avoided.
It's also clear the communication and honesty in your marriage wasn't what it should be (at least from his part). But you wrote: 

I often wish I didn't know, I'm sure you've all felt that way... 

I understand what you mean, because of how you feel at the moment and I sympathize with that. But I don't agree. Because before the honesty wasn't what it should be, the communication wasn't going well, deep feelings weren't opened up.
Not knowing would be living a life that avoided much of what/who your husband is, and also sharing yourself and your needs and feelings. Don't get me wrong, it's not your fault your husband is the way he is and acted the way he did. But you could also approach this crisis as an opportunity to get things right, that otherwise could have dragged along (for whatever the reason of it). 

When my wife came-out to me being lesbian, my world came crashing down, it was awful. It felt like the worst that could happen to me. And indeed I was totally unhappy and very anxious, it sure felt desperate at times. 
But we went for it and came through it. Now I look back on it as the best thing that could have happened to me (and for my wife that's the same). A crisis always means suffering, but it can bring about that changes you would never have come to in some ordinary easy way. But again it depends on how you BOTH go in and through it. If one just sees this as an opportunity to his/her own fulfilling at the expense of the other, it will bring only harm.

From what you write I get the impression your husband has the intention to go for you and your marriage. There are positive aspects in what you write about how he now deals with it and what he tells you about his feelings. But I certainly understand your feelings too, not much different than me or anybody in your situation. 
But you know your husband best, not just his sexuality but the complete person. It's hard to describe the all important prerequisite, but I think I somewhat can describe it with a question: "What is his true legacy he wants to leave behind?"
The honest answer to that question will tell you whether it's wise to take up the major challenge to make a MOM succeed. (and of course it's also up to you whether you want it yourself in the first place).

So tell me, how do we move on? (Together... I know the other option but I don't want to travel that path until I've exhausted the potential on this one.)

Wow, now that's a direct question if there is one!

Some main ingredients you know, and even experienced a bit. Acceptance, open and honest communication (and thats rewarding!). You may think it's already quite something, but you just started.
Don't expect this to take some months, it's probably more like years. The open honest communication thing, should be there to stay  
Are you there yet? Is he totally open? Are you? I don't think so, it takes much time to develop it. Really being open and honest is so much more difficult than it looks like (or we are willing to admit to ourselves).
And there is also the complicating factor that we don't want to hurt the one we love more than is needed. It's a complicated dance to get there, and it takes lots of time and talks.

The sexual relation is another thing that is important. To my opinion its necessary to keep intimacy alive in a marriage, most of all because that is a special aspect you only share with each other. And it's delicate and precious, so a workplace for love.
It's an easy way out to let this go when homosexuality turns out to be part of the marriage. But I really think allowing not to be sexual intimate is a sure way to break down the relation over time.
We consciously decided to keep our sexual relation going. Aware of the lacking physical passion from my wives side, but still out of love for each other. Is it a strange thing, having sex out of love?
Well, we just made the best of it. It was not what it could be, but it still had good and certainly had love and caring in it. Because the intentions were beautiful on its own right. It's necessary to talk this over well, being sensitive and caring about the other, finding some way to make it work for both sides.
Again: lots of talk and communication! But keep trying to build a bridge to each other, also through sexuality. Limited as it may be, don't give up on it. The focus is on the importance of the other and what you form together, this is the joint venture you share aka "love".

For us it turned out sexual feelings developed. Somewhere out of the blue, and we didn't expect it. It seems that if conditions are right, sexual orientation doesn't mean that much. 
Flowing love and connectedness, being open and accepted, being true to each other and the bond and importance of the other in marriage. That is key. It may take some time to discover, but that is it.

It's so understandable you need time. You have so much to process and that's not only rationally and trying to understand your husband, but also the emotional impact this has on yourself.
You should allow yourself that, without feeling you're supposed to do that more quickly. I'm sure your mind is making overtime, so it's better to take a daily walk and put some relaxing into your schedule than rush.

Your husband already had a lot of time to think things over. It's somewhat understandable he now feels like "move along", but well, that is not fair nor realistic. Because he knows what he feels, has access to it so to speak. 
But you have to figure it out through talking. Next to all that, you yourself have to deal with this totally new situation you're in. And that's a lot! I've been there and I surely know and understand. 
It would be helpful if your husband understands more and better what you're going through. Maybe couples therapy can help with that? A therapist understanding your situation and conveying it to your husband, helping him to understand and be more patient while you give things a place in yourself.
Or even just you writing a letter/mail or something to your husband, explaining your thoughts, fears and feelings.
He may have got some grip and understanding on his own sexuality, but he's not informed about you in all that. That's a new aspect he has to think and learn about. How to deal with his wife, and her feelings. That is about the actual now, 
I hope he gets that, and you both get more in sync, dealing with this together.

There is so much more on the road ahead of you both. Don't rush, take it a step at the time.
Trust will return if you both go on that way further, but accept what it is, as it is, for now.
