So, I met a guy online, and he is interested in me. I begun to like him but I backed off after he told me he still talks to his ex girlfriends and he babysits one of his exs' kid occasionally. He says this woman is his online business coworker, dated for a few years. I feel it is inappropriate to keep being close friends with exes unless there is absolute trust in each other with new romantic interest.What do you think?
