My boyfriend and I have been dating for 5 years, soon to be 6 and plan on getting married one day. However he has serious problems with a one night stand I have had in the past, before I ever met him. I have lied to him about it, altering it so that it does not hurt him so much, even though I have lost my virginity to my boyfriend now and such, I just feel it is unhealthy the way he is so worried and upset with me over the issue. However, I feel bad hiding this from him, but feel it is unnecessary in our relationship. I know it will hurt him, and be an issue in the long run that I feel is easier to avoid. I just want to know if I am wrong from keeping the details from him? It had nothing to do with him, and is not something I could change anyway.
