Wasn't sure if I wanted to put it out there, but I needed a place to let it out. I suppose my situation was too good to be true. Dated for years, but the marriage itself did not make it to a single year, at least unofficially.
It's been a stressful time. She previously had a government job under an agency that doge culled. She loved her job. I realize that as a society we work too much, but to some degree people do want to feel productive and that many people find their workplaces to be places of belonging. She apologized for taking so long to come to this conclusion, but she mentioned that this time away from work has helped a lot with self-reflection.
I was aware that she considered herself bi previously and that she had relations with women before. I wasn't aware of the extent of it. She told me she felt compulsory heterosexuality for a long time, but wasn't entirely sure of it and I was her last chance in regards to men. She told me she still loved me, just not that way, and that I was the best partner she'd ever had, that she was remorseful about not being compatible in that regard. We discussed a lot of more private feelings, mostly trying to understand and showing concern for each other.
I support her. If that's how she feels then that's how she feels, and she deserves to be happy. I'm not angry with her, and we're not leaving each others lives, just changing roles. It still hurts a lot, but that's life sometimes. It isn't anyone's fault.
That said I'm glad I won't be doing anything tomorrow. I'm just struggling to function right now. And yeah, that's how it's going.
Edit: I slept in today quite a bit. I've read through most of the replies and it really melted my heart. I cried a bit. I didn't expect so many kind words or this much encouragement. I appreciate a lot of the advice too. I don't really know how to express any gratitude beyond this. I will try to reply a bit more later, but I need to take some more time to myself for a while. Thank you.
Oh there were signs in the last few months for certain. Like I mentioned before, she's been out of work, and depressed, so that masked a lot of the hints. I have noticed that she seemed as if she was genuinely trying to prepare me for this in some ways though.
Bedroom wise we both initiated quite often. She tells me she doesn't regret any of it, and she says she's confused as to why she enjoyed it sometimes more than others to the point where she eventually couldn't feel like doing anything. A lot was reciprocated, we've always had a policy about fairness.
