Bad relationship with my boyfriends family??? HELP!?

[Cherish H.]

In November of 2007, their was a huge lie that my boyfriend's obnoxious pregnant older sister told her mom that I had done. Nothing bad, just how I supposedly pushed her into doing something she didn't want to do. I am a good person, and I would never do that.
However, her mom bought it and ever since that , I am not allowed to be at my boyfriend's house when his sister is there because she is still making it out to be my fault on something that I have no part in whatsoever.
My boyfriend's older brother came home from Korea (hes in the army) about three weeks ago and left this morning but yesterday when I said I would stop by the tell him bye since I hadn't seen him the entire time he was home, his sister pitched a huge fit and I couldn't stop by to even tell him bye.

This just looks like a disaster waiting to happen with my boyfriend. I mean, how should I handle this? It seems as if this will only cause problems in the future. But I love him, please help. What should I do?
My boyfreind has said many things to both his mom and his sister. However they treat him unfairly compared to his older brother and sister as he's not blood related. His real mother left him when he was four and that is his step mother, brother and sister but supposedly they dont look at it that way. Thats why his mom took his siters side. and yes, she is very spoiled and obnoxious.
???? its dumb, i know. i just dont know how to handle this.
i feel uncomfortable even calling over there.

are they trying to get rid of me or something? i mean this has been going on since november.

:S

your boyfriend needs to have a talk with his family especially his sister to see what the hell is bothering her so much about you
you would think though that your boyfriend would have a say so on your behalf also .....
