Giving the Boot

Ok so my cousin's BD is a pos and needed a place to go. I told her she could stay here, but she needed to be looking for a place while she's here. She's only been here a week and I'm already at my breaking point. She doesn't clean up after kids, she leaves dirty diapers all over the place (GROSS), eats all of our food, uses my phone more than I do, and doesn't want to follow the rule of her BD not allowed to be here when my fiance isn't home. Well we went to see family for Easter yesterday and she didn't come home with us. She had a ride set up for her today, and still refused to come home all because she wanted to see BD. Now she has no way home, and expects us to come running. Not happening. Fiance is pissed and wants her gone. SO DO I. Is all this grounds to kick her out or should we let her stay?

Its your house and your rules. If she isnt willing to respect that then she shouldnt be in your house. Sit her down and tell her EVERYTHING that is bothering you if she doesnt change it in a week tops then tell her she needs to go.

I would tell her to find a ride to come get her stuff and get the hell out.
