Should i break up with my boyfriend if he makes me feel im not good enough?

been seeing my boyf for 6 months now...i only see him at wknds...he always wants to see me and wants me to meet his mother...however some of his actions annoy me though..when hot gurls appear on tv he comments on the size of their breasts etc and says their hot but he says it in such a way that makes me feel like its a dig at me...im a tiny girl and size 30c and think my boobs are perfect for my body yet he still makes me feel like their not big enough...he stuffs objects down my top for a laff and says thats better..along wit loads of other comments about my size...they were always that size so wats his problem!! .im now realy self conscious about my appearance...over the wknd he commented on 3 gurl son tv...now i kno that they are threats or anything but i feel like hes saying to me theyre hot and your not!!! im very attractive and have no trouble meeting guys and i think hes very jealous of that....when we first got together he coudlnt believe i wanted to be with him and said i was his perfect girl...now it seems he puts me down every chance he gets...he says other things like you plucked your eyebrows wrong, ur hair is thinning on top, ur skin is terrible.......if i say i dont like wat he is saying he says thjat i should kno that he is only joking...he comments on other gurls appearance a lot in a good way but always has negative things ot say about me...so why is he with me,,,we get on really well other that he says we were made for eachother ...he is happy out but he maken me feel like crap....p.s. im very insecure anyway i always compare myself negatively to other gurls but he is maken me worse ...iv told him commenting on other gurls bothers me and he says he wont do it anymore..he is also quite physical with me he slaps me playfully but i dont tink he shud raise his hand to me at all .but i believe that ppl cant change
