Should I believe that he doesn't like them?

I have a boyfriend, but I always feel like he flirts with other girls and likes them more than he likes me. He always denies that he doesn't like them but I don't know if I shoudl beileve him or not. What should I do?

If he was my boyfriend. and I truely wanted to be with him, id do it back when he was around and see how he acted about it. and if he said something id set him and down and tell him how do you think I feel? you do that to me. and see what he says.

well if you really feel like hes flirting with other gurls and like otha girls more than you you should try to at least try to make a solution for both of yous or you can always go for revenge if he is truely flirting with other girls fight fire with fire what comes around goes around
