Synergy...welcome to the forum. This is an earth-shattering, life-changing event. Nothing will be the same ever again. And just like there are men and women who hear this news, of their partner being gay/bisexual, and immediately know it's not going to work and they have to leave....there are husbands, wives, partners who want to explore every avenue in an attempt to make it work.
You don't say how long you've known but it's not something that you can absorb into your r'ship easily. It takes communication, open and honest...with nothing held back.
If you can find others who live close to you who are going through this too...more power to you one of the hardest aspects of this bombshell is the straightspouses lack of having somebody who knows exactly what they are dealing with...to talk to face to face.
I'm in New Zealand. I have nobody to talk to face to face who's going through the same thing I am.
I hope you find that support.
