My boyfriends family hates me

My boyfriend and I have been together for about 8 months we fell in love with each other right away. My cousin had set us up, my cousin is married to one of his family members. My cousin and I did not speak for 5 years following things that happened after my mothers death when I was 16. I reached out to her after 5 years wanted her in my life again because we were very close before my mother dies and I have no family but my older brother.

I did not get off on the right foot with his family from begining his sister did not like me because she of stupid reasons but I was never told this by her, I knew it was true but her and I never spoke about it all of this was going back and fourth trhough my cousin. I was venting to my cousin the entire time, of course I was upset I couldnt understand why they didnt like me, I did nothing wrong to them and the things I was being told from my cousin how they are really tained my vision on them. Eventually everything blew over and his sister and I started having somewhat of a relationship and I was starting to build a relationship with his family (whom by the way fights with everyone, my cousin told me numerous stories and I have seen it for myself, no one in their family talks to eachother).

Being around his family and hearing stories of what my cousin told about me and past and what happened it was not true or partially true but switched around to make herself look better, so I told my side to his sister. My cousin and his sister are friends and his sister used to complain about my cousin to me when she did stuff wrong to her, which majority of the time his sister had very valid points. Recently my boyfriend comes home and tells me my cousin went to his house and told them all these things about me and things I supposedly said their family, some of the stuff I did say but she manipulated my words and made it worse then what it was. He family hates me now and belives everything she told me, which I dont think is right because my boyfriends mother has told me my cousin isnt a good friend and his sister has told me my cousin is liar.

I have not been able to sleep I am hardly eating, I am so upset over what happened. I dont know what to do. It is effecting my relation my boyfriend knows my cousin is lieing, he knows that she has a split tongue he has been there when she said things about people in his family and now she is trying to say I said things. The bottom line is his family hates me now and does not belive that I didnt say those things and that I am not the person she portrayed me to be. We love each other and I want to spend the rest of my life with him, but I dont have a big family it is just me and brother and famaily is so important I have ALWAYs wanted a realtionship with my boyfriend and one day husbands family but now she ruined it. I dont know what to do. I belive his family had it in for me since day one and this is just something for them to dwell off of, but I dont know if my boyfriend can handle me never having a relationship with his family. Should I walk away from the love of my life because of his family or should I tough it out?

You and I are in similar situations... however,, I do deserve to be on thin ice...but have learned from what I have done..and want to be forgiven and accepted..but ..unfortunately I dont think that can ever happen again...so I have to just let it go..and realize that ' it is what it is' ...nothing you can do can change a persons view of you ...and if your boyfriend truly loves you ..then that is all that matters... just try to stay on the good manners side with them..dont get too deep ..and never get in a situation where you have to live with the boyfriends parents..
the future will take care of itself...and there is no rush in love or marriage anymore... so its when you two are ready ...not the future family in laws...
Good luck...
