Boyfriends Family and working

applesock

ok here goes , ive been with my boyfriend for 6yrs. The first couple of years of our relationship he didnt have anything to do with his family and wasnt bothered ( bit of a crappy upbringing ) , over the last couple of years he's started to see them more, ive always made an effort but there just not nice people. The first time i met his mother she had a fight with one of the brothers and started throwing bottle of beer around the place !! at this stage i told him i didn't want anything to do with his family , he agreed, i couldn't help thinking that it years to come if we had children and that type of person would be their granny , i just couldn't deal with that.

The final straw was this weekend got talked into going up to the country to see his brother so him & his two brothers & their girlfriends. I just couldn't stand it , there just so loud listening to rave music etc , driving their cars around with the music blasting out and spinning around in cars on the green areas. Now if i saw other people going on like that id be like there acting like scumbags ( sorry if that's abit harsh just my opinion ). My boyfriend would be quiet spoken and a good laugh but when he's around them he nearly acts like them , then they all started taking drugs except me and there was kids there!!!! On sat i couldn't even speak to any off them they noticed but if i was to talk i was going to say something id regret. Was watching tv and his brother started to slam the door that separated the kitchen and sitting room ( according to my boyfriend i was throwing them looks because they were playing the decks ) i dont actually remember this then i made a comment about the winner of BGT having six packs and joking with the OH that he was jealous, and how they not on stuff & his brother shouted quiet aggressively at me asking me how did i no if they weren't or not taking steroids. It was only a joke !!
anyway were home now slept in the spare room last night , my OH started saying stuff to me today mean stuff so i told him his family are scumbags ( just my opinion ) i no that's harsh, but i no he knows it himself, but i actually cant deal with them and now his older ( no better than ) brother is getting married in September, i cannot go to that wedding . But can i really split up with my boyfriend because of his family? or has anyone any advice on how to even deal with the situation? i do love him i just don't love his family and now im not sure if i can even tolerate them.

also he's only started doing a work placement job that he loves but because all his family don't work he doesn't seem to think he has to this has been an on going battle over the years and the only thing we fight about its draining. I no the upbringing has effected his work ethic but cant keep blaming the past on your future. i dont no if i can do it much long.
but like i said i do love him

thanks in advance for any advice.
