I can't stand my sister in law any more

to make long story short, I feel like she comes around only when she needs some thing and after she gets what she wants she ignores me and my husband and hangs around with her other brother that don't to shit for her.... so when I get mad she states that I am jealous and she goes where she wants to go..... me and her are always argueing over stupid s###... but that's my husband's sister so it's hard to just forget about her... all i want is piece but with her that doesn't exist she causes all of the problems and then pins it on me.... and his side of the family turns on me and custs me out... I'm tried and sick of this l, it's been going on way to long....i love her and I don't know why all she does is lie, spread rumors about me and make my life a living hell.
