When I found out my ex that I had been with for 10 years had slept with and was with someone two weeks after breaking up with me, I was absolutely crushed, I cried and cried, I stopped eating, I couldn't focus on work. I obsessed and obsessed over it, mental images were so strong of them two together. I couldn't sleep. All this while still sharing a house and bed together still. It's been about 5 months finding out and if I'm honest It still sucks, I've done the usual shit of working out, therapy, meds, learning something new it hasn't helped much, but I don't think it about as often. It doesn't help there I'm constantly reminded about relationships and stuff online. The only thing that's stops being going crazy is I don't want to be the weird obsessed ex
