Please help! is it me in the wrong? or am i right?

You're behaving very immaturely. Most people have a history and you don't really have any right to start slagging off this ex girlfriends especially saying petty comments like how bad looking they all are. You just feel insecure because he has a past and you keep wondering whether he prefers you to his ex's. Well OBVIOUSLY he loves you loads otherwise he wouldn't say all those nice things to you and move in with you and treat you well. Grow up and get on with it!!
