God!! i really need help....

my sister in law is always trying to brake me and my boy friend up and saying that ue is cheating on me and sh!t like that but me and him are always together, during the day we are hanging out, then after he goes home, we are either on the phone talking or the internet and she just wont stop and i told her to stay out of our relationship but she doesnt listen and she is stressing out my boy friend and he told me that if she dont stop, he is going to brake up with me, what should i do??????please someone or anyone help me!!..

i think she is doing this because she dont like him, she has never liked him, he always told her whats on his mind even if it was rude, he didnt care and he wasnt scared to stick up to her, but i dont really know why she is doing this.

i do, but he always gets pissed off at me and her

if she doesnt like him, then walk away!!!! ignore her even if ur BF wont because there should be some way for the both of them to get along.
