My Drunk boyfriend

I started daiting my bf  6 months ago so adorable, sweet, caring, nice sex, very nice guy,  his friends are nice and his family everything seems to be perfect between us... I always knew that when he drinks alcohol with his friends he gets crazy goofy BUT my problems is that every time that we drink together with my girlfriends he gets attractive to them saying stuff like you girl friend  is so Hot or she's so sexy , Or flirting with  any other girl in front of me ..Seriously ??? It makes me really upset  and the next day he doesn't remember anything... Yeah right.... He always sorry saying it won't happen again that I'm so dramatic  ( of course it did happend already) with another girlfriend... So all my gfriends agree that I should break up with him because he a jerk ... How can I Do??? Any suggestion ???? I love him :( Ughhhhhh
