I don't know why I keep feeling like this
Hi so to put it simply I was broken up with about 10 months ago, it was a 7 year relationship, my X had a bad living situation and I gave her a place to go, I gave her as much as I could and listened and helped in every way that I could, we had a few arguments here and there, we would talk it out and try to find understanding, I had a rule thay I would try to keep to of not falling asleep mad at each other. And one day she just kinda stopped trying. I don't know if I was cheated on but with how everything happened it just seemed to coincidental that she was seeing someone in the same week. I'm working out (down 40 pounds from 230 yay) gotten into hobbies, but I just keep finding myself looking back and trying to figure out what happened to everything, It's the sunk cost fallacy, and I also keep thinking that it's doesn't matter even if there was something going on, but I feel like part of me just wants to know if that person I loved ever existed or if I was just used because I was convenient. I know no answer will make me happy but god I just feel so empty when I think about it. I don't want to think about this anymore. I just want to move on and find new people but it feels like I'm being haunted by it. Thank you for taking time to read this and sorry for any grammar mistakes.
