My BF's family HATES ME?

He has 11 siblings, (12 in all counting him) His oldest sis. Think that I tried to copy her sis Nikki because she has a tattoo on her back and I got the same exact one. When she changes her hair style I do it to. And they claim that I'm a Nikki wanna be. Her eye brow is peirced and I got mine peirced too. But me & Nikki are close. She's about the only one : His younger siblings like me too. But his little bro. Sunny hates me. He says I wanna be like his sis. His oldest brother as well. Pretty much everyone ex. his younger sibs, his sis Nikki and his mom likes me and his mom likes me about from a scale to 10 maybe about a 4. But his step dad is a hater of mine. very time I come down his oldest sis says 'Why you follow my brother here?" She see's him and hugs him like she hasn't seen him in a while and just give me that look. she doesn't even want her kids near me or calling me "Aunt" she says i'm just a girlfriend and that's all im gonna be. she likes the rest of her siblings boyfriend/girlfriends. and him and me just argu he claims he needs space. and when he gets mad at me he says "That's why my family don't like you. You ain't nothign but a wanna be trynna be like my sister." or "that's why DM said I should have left your *** and got a real women." Dm is his dad not his bilogical father. Mlther's husband. I feel the tention every time I go to their house. I even feel it from him.I'm always getting cussed out by atleast 5 ppl at once. Help me. I think he wants me to go as well. It's not his family it's me. They did like me when we first met but now ... IDK even his friends hate me.
