I have been dating this great guy for about 6 months now. We had everythign going great for a month then he started to get insecure and jealous. This wasn't a little bit, it was major big issues to our relatioship. I love this boy with all my heart and I am all the time trying to show hi, my affection but he thinks that I do things behind his back or want another guy. He thinks that when I get my vehicle that I am going to cheat on him and I have told him over and over again that I would nvr do that to him ever! It just won't get through to him. He has never raised a hand to me and he is on some medicine that we think will work or is hoping St. Johns wort but I just don't know what to do anymore. I try to tel him my feelings and he just doesn't believe or trust me. He promised to do so but won't. I don't want to leave him, I just can't bring myself to do that. So how can I show him and make this work?
