He was a family frienand we had a thing going for about a month or so. And at first he acted like he liked me a lot but then he started distancing himself and when I asked him about he gave me all these cliches that he wasn't ready and I deserved more etc. well fast forward to 3 months later and he is seeing a girl he met while we were dating and making all the effort he didn't make for me. We had gone back to being friends but now that I have this new information and see him with this new girl I feel hurt and like he lied to me and like a fool for believing what he said. Should I say something to him? If so, what?
