Shit, that sounds awful. I'm glad we didn't have any kids involved. Sorry you're going through that.
Incredibly painful and had me borderline suicidal at the time because I had ZERO friends or support in the city we'd moved to for her job, I'd only lived there a few months.
Mostly doing a lot better these days, after a lot of therapy (I had other shit I was working on in therapy prior to the cheating, I was 6 months sober when she cheated on me. It almost broke me but I kept the streak, still not a drop of alcohol to this day), then I said fuck it and moved 1000 miles and restarted my life about a year ago.
I definitely still have trust issues though. The idea of dating again still makes me anxious enough that I've only been on one date since moving here.
Oh and somehow she's already married? So fuck me even more lol
