I didn't have a problem with her before but now she's turning trying to stir up drama (with me).

A long time ago my husband (then BF) used to hang out at his parents house, she would just open his room and start talking nasty about the other brother but until we met him out in cali he was actually a great guy. She managed to make everyone at home believe he was mentally incapable and something wrong with him. She came in drunk with her BF told us to leave the living room(we didn't want to fight drunk people so we just left), we didn't see it get broken but the parents table was broken and somehow her parents thought it was us (I'm tiny and quiet and DON"T drink! I let this go) We were hanging out once and she didn't know we were there, we heard her say nasty things about me and my husband on the phone. So I know she does this to make her seem better. She invited herself and her BF to anything just to talk bad about my little bday party. and how her's is going to be better and what she's NOT going to do it like mine. She's 26. I can't keep her out because she always comes with her parents, and we invite her parents.

I got married and now her family said things about how the ceremony was flawed and how my husband should've done things a certain way and how he treated people and how I didn't talk to his sister that she cried. (His mom is NEVER like this she is professional , she is different, and it's weird) I ignored his sister and I could hear her whispering she was critisizing the way I looked. mother in law called him and made him feel guilty and now he's depressed. I can't get rid of her, I need to confront this issue but I would hurt the whole family, to confront or not?
