Hi BobOn - are you still there?
I'm a longtime (9 years) lurker, but namechanged for this just in case anything from my handful of posts on MN in the past could identify me.
My DH (I'm a woman) came out to me as bisexual two weeks ago and I have been scouring Mumsnet for helpful threads. I nearly started my own, and then stumbled across this.
In our case, the revelation was initially something of a relief, because I have always suspected DH is bi. My fear was that he might actually be gay, which would mean the end of our marriage and my life as I know it.
I was so glad that he was finally being honest with me that, initially, it felt amazing to have this out in the open between us, although I was sad that he hadn't been able to talk to me about it before.
We have been talking a lot more than we ever have before and he has reassured me many times in the past couple of weeks that he is committed to our monogamous relationship. Yet, despite the fact that I believe him and trust him on a rational, thinking level, I have been surprised at the strength of my subconscious reaction and how insecure and vulnerable I am now feeling. He has never had any kind of emotional or sexual relationship with another man, and I am terrified that this is something he might need. He says he doesn't. He says he only wants me. But I can't stop thinking that I am only half or part of what he needs.
So perhaps my feelings are similar to yours. And I, too, am interested in hearing how other people have navigated this in their relationships.

My problem seems to be a disconnect between what my brain can understand and believe and how I actually feel emotionally. I think that for DH and me the answer is time and talking. But, like you, I don't have anyone in real life I am ready to discuss this with. DH hasn't told anyone else, so I feel that it would be weird for me to talk about with a friend before he has.
Anyway, that got a bit long, but if anyone out there is willing to chat about this then I would be grateful.
