How do I trust him if he has lied before? My boyfriend and I have been dating for about a year now, and he seemed like a really nice guy. I recently found out that he has been talking on the telephone and going out with a female whom I have had previous complications with in a past relationship. She has been the other woman in my past relationship and I believe she is trying to become the other woman in this relationship as well. My boyfriend knew that we do not get along well at all and still proceeded to see her. He states they are just friends, and he has a right to have friends, but only AFTER I caught him doing so by accident. He then proceeded to lie several times why they are around each other. He says that we have gone over this several times now and he no longer wants to talk about it and that he is not going to see her anymore. How can I believe him after he has lied so many times about it and is pretty good at covering his tracks. I don’t know if he actually cheated or not, but how am I supposed to trust someone, who lies about the whole situation, and how am I supposed to believe that he is not seeing her anymore?
