My past is hurting my boyfriend-help
So my boyfriend and I have been together for four months; but we have been friends for 12 years. I just recently told him about everything in my past and it's hurting him. A couple of weeks before we were together, I did something I shouldn't have done with another guy. I realize my mistake was completely stupid and I can't believe that I didn't see anything bad about it. He's worried that my past still might be a part of my future since it was so recent. He tells me that he is unsure of who I really am. I hate having to see him hurt because of my stupid mistakes--especially since it was so recent. I am unsure how to prove to him that I see what I did was wrong and I plan to stay away from that same mistake in the future. But how can I prove that to him when I don't have any evidence that I've changed? I started talking to him a couple of weeks after the bad incident. Should we separate completely and see other people to see if the same situation comes up? Should he just accept what I did and trust me that I have changed even though there is no proof? I also want to know that I have truly changed, myself. In my opinion, he is not wrong at all about worrying of this. If he wasn't worried, that would actually bother me. Help would be great. Thanks.
