My ex stopped communicating with me and was just full-on communicating with her best lets call him Zack instead. I would text her and she be texting Zack instead, I asked to call her and she would say no because she's in a call with Zack. So I got upset after awhile and told her to do that with me more and she said no than acted like I committed a crime and was threatening to withhold sex and telling me that he's more important than me and that she has more fun with him than me. Than tried to pass it off like I am insane and the bad guy. She hurt me hella badly so I told her how she made me feel and she left me.

I still miss her she was everything to me, she would make food, had a nice body, great at sex, and we had the same fetishes and I miss that so much and I cant help to think about it even when I do things I love. What do I do?
