I wish I could give you advice. There are a few posts out there of mixed orientation marriages that worked - but from personal observation those couples did not have infidelity and both partners were fully invested in making it work. And even then, it was still hard.

My ex came out as "bi" several years ago. Complete slap in the face. I had absolutely no idea. He too assured me I was the only one for him, he just wanted me to know, it meant nothing, he was committed and wanted to stay married. I was on the verge of leaving....and there was no infidelity. For me, it was the lying about it for years.

But I stayed. He begged me to stay. All the "I can't live without you". I listened to all the "I love you" and "I only want you" and yadda yadda. I believed him. It took me close to two years to trust him again. But I did. I changed so much about myself. I did all the counselling. The talking. Planning the future. And, after the grueling tortuous experience that that all was....I was finally happy again. I did not realize just how screwed up I was.

What did he do? He used those years to lie to me, gas light me, manipulate me. Basically, he took that time to figure out what he wanted. Decided he was gay, not bi. Detached from the relationship. And he went through all this without saying a thing to me. There was no discussion, no concerns brought up. To the bitter end he lied to my face.

Then he sat down beside me on a Saturday, looked at me and said "I'm gay, I'm divorcing you". He was not open to any discussion on the matter. There was no compromising. Hell, there wasn't even time to begin to absorb what the hell just happened before he had moved out. Over the next few days he proceeded to tell me that he wasn't in love with me anymore. He saw me as no more than a friend. He had 0 attraction to me. He wanted to have an intimate relationship with a man. He wanted to find true love. I felt like he was just repeatedly sucker punching me in the face.

We had been together/married for 18 years. So, now I'm alone. He drained the joint account to pay for a new apartment and move etc. I am now responsible for all the bills that we used to pay together so I work an insane amount of hours a week. And I'm left with the "mind fuck" that he left behind. And now I have to go through the divorce process.

So, what I learned from all this is.....you do you, first and foremost. Take a step back from the relationship and take the time to figure out what YOU want. Separate from him. Do you want to be with someone who cheated on you repeatedly? How do you feel about the trust level in your relationship? How do you rate his level of involvement?

So, I admit I am skeptical about these relationships working but if you want to give it a try....make sure you look out for yourself (and your kids).
