My SIL is the most selfish person I have ever met

I don't know what to do this is really making me crazy and my husband just won't put this bitch in her place... She is so selfish and manipulative all she cares about is her self and her son...she constantly comes to my house, spends the night, borrows My clothes/makeup, eats our food, borrows my husbands car, expects us to babysit and chauffeur her and lie to the rest of the family for her and it's getting ridiculous...I already blew up on her and almost got physical and that kept her away for maybe a week...she weasels her way back in slowly and guilt trips my husband into letting it start all over again...he knows how I feel so does she and after jumping down her throat and almost across the room she is back at her old games again...it's gonna come to blows soon I can just feel it and my husband still won't put her in her place and tell her to fuck off for good...he's such a pushover with his sisters it's insane and then I'm the bad guy because I don't hold back and just let them have it...but no matter what I say she goes behind me and ask my husband for favors etc...will this ever end? Idk how else to approach this my other sister in law is not near as bad and she even agrees with me on most stuff no one in the family can stand to live with her or be around her for to long because she just is the type to come in your house and make herself at home she wears out her welcome in less than 24 hours it is insane...should I just tell her idc what your brother says don't come around I mean she knows what she's doing she knows I hate it why would someone stick around where they aren't wanted???
