Was he honest with you, and tell you about his Ex Girlfriend in the begining of the relationship? Seems like you had allot of trouble trusting him, without trust there is no relationship. I think his ex girlfriend is the one tearing up the relationship, has he told her to leave you guy's alone? I went through this with my boyfriend and he kept telling her to go away, but she wouldn't, she kept hurting us, but I learned how to ignore her because he is with me. He had allot of trouble letting her go because she was in his life for years, but i knew he genuinly loved me, because he sat her down and explained to her that he was in love with me. I feel bad that you are in this situation, because I know how much hurt is involved, You will know in your heart if he genuinly loves you.
