Not good enough..

Lately I haven’t felt that I am good enough for my boyfriend..all he does is look at half naked Instagram models all the time..we have talked about it and I have expressed how I feel about it..he just always says that I am good enough and they don’t matter..but if they didn’t matter and if he was happy with me I don’t see a reason for him to looking at other females half naked..just rlly want other people’s opinions on that and before anyone says that I’m just insecure and need to get over it like most people have told me I come from an abusive background and always being told I’m not good enough etc..I don’t want any sympathy or anything like that I just thought it was fitting to tell you so you can understand my situation any input or help would be nice at this point
