I want to end my relationship. I'm tired of the anxiety it brings me. I feel constantly like I'm easily replaceable. There's so much insecurity, and I'm unhappy all the time. The thing is, I'm really in love with my boyfriend. He's everything to me. Ny insecurities stem from the feeling that I'm not as much to him, that he'd easily go on living without me. I hate it. I hate the feeling that whenever I leave, he just hits up another girl friend. I hate the feeling that I don't make him more happy than others do. He told me my behavior was abusive towards me. He even rejected me few times, and the wounds I feel I cannot recover from. I feel like a burden and I just want to disappear from his life. But I don't know if this would be an irrational decision. I don't know if this is just my insecurity.
