my heart is breaking

my bf friended his ex again. i keep confronting him about how it bothers me that all his exes r still contacting him but he does is shrug it off... his most recent ex bothers me the most. she was once pregnant with his child. she has made remarks to me about how he doesnt really love me and it bothers me. then she'll usually remind me that she once carried who wouldve been his child. he is still broken-hearted over it. i know that for a fact. well the ex before her has been texting him asking if he still wants her. he always says no but she still texts him and he replies. he just friended his most recent ex and it puts doubt in my mind that he really wants to be with me. i keep feeling as if he still loves her. i dont have much to offer him. i have anger issues and trust issues. i cant concieve kids. i hate amusement parks cause im afraid of heights and the feeling of falling. im super clingy and i fear im abusive at times. though i havent hit him before. we just recently had a pregnancy scare and all he could tell me was he didnt want the baby if i was. all i wanna do is cry. i just feel scared of losing another person i love. another year of wasted love poured out to someone who isnt listening...
