Me & my ex were together for 7 years. The relationship became really bad and we broke up. 3 1/2 years go by and we happern to see each other again. We start talking everyday seeing each other 3 4 times a week. Things seemed weired but OK to get back to being comfortable with each oter. It was like we saw each other yesterday not that 3 1/2 years have gone by. Oct 2nd I left his apartment and haven't seen him since. He won't answer the phone for me he won't answer my text and he's texted me may 5 times. So my question is what happen why won't he talk to me anymore?

Maybe he's busy or, sorry to say, don't want to be bother by you. Only he can truly answer that question.

Maybe being with him reminded you of old times and maybe that was weird to him.

Question is why did it end 3 1/2 years ago?

I don't think he feels the same as you, and isn't interested in renewing a relationship, or he is a very rude, inconsiderate guy, and you need to take the hint, and leave him alone. Sorry.

I have a weakness of always giving people the benefit of the doubt. BUT I also do not believe that someone is SO BUSY they can't make time for people. If he has been ignoring you and flat out not answering your calls sense oct 2nd.. He doesn't deserve you in a relationship, BUT EVEN MORE important, he DOES NOT deserve you as a friend.
