Am I just pmsing :(

I have an ex who I was with for about 2 years. We had a stable/good relationship until the beginning of this year when my bestfriends boyfriend passed. He got mad and was acting jealous because I was spending most of my time with my best friend. He was also jealous that I cried over his death (because I claimed I didn’t know him like that/ he was “only” her boyfriend). We started arguing a lot after that and just started having problems and broke up. I was starting to think I was getting over him, until now. The first few months I cried and missed him a LOT, literally thought about him all day while sulking in sadness. As weeks turn into months, I start feeling normal again while occasionally having those sad moments about him.

Well today, I’m back to the mess I was just crying and thinking about the relationship. I want to think it’s my PMS since my period should be starting soon but I’m feeling like it might also be suppressed feelings. I also wanna add that ive been dating but it seems like sex is the only thing they want and they’re just not him :( . I know I don’t wanna get back with him either so why am I crying😩
