I need help and advice. I'm considering telling my ex's new girlfriend he has cheated on her with me multiple times and still wants to just sleep with me because he misses the sex. But the thing is I still feel so betrayed but both of them we had a house together my first with anyone other than parents and he moved her in after two months. His new girlfriend has been his friend for years I always said that he wanted her and he always said she was just a friend and weeks after we broke up they got together and he does things for her and with her that he never did with me and that still hurts as it makes me feel I wasn't good enough when I have him my everything and more and he left me and gets to have the happy ever after but I just don't know if telling her would help me would it help let go of him n all the memories he has ruined for me or am I just still the fool??
