I'm crazy in love with my bf of 7 months and recently my ex gf and I have started talking again and I don't honestly have feelings for her but I kissed her. Although I am starting to have feelings for her but we broke up for several reasons I'm not gonna say cause I promised her I would never say anything. I honestly don't know what to do. My bf and I have have no problems we fight but we haven't had one recently. Is it cheating ? Should I tell my boyfriend ?
