Okay, so me and my fiancé live with his parents right now due to our financial situation. I don’t personally mind it because we have the whole basement to ourselves and his parents RARELY come down here. His sister is 16 and she spends a lot of time down here which is what it is. But it’s to the point she’s been taking my clothes, my chapsticks, my makeup, my fiancé’s nicotine, and it’s to the point I don’t want her down here at all. I was doing laundry today and she had been wearing my favorite pair of pajama pants. She tried telling me they got mixed up with hers and her parents laundry which is false because they have been in my dresser. I went to wash them because they were laying on the floor of the laundry room and when I picked them up there was a bloody pad attached to them. She immediately got defensive when we asked her to take the pad off and throw it away and tried to say it was mine and then her moms. I’m 6 months pregnant and their mom no longer gets a period. Am I wrong for telling her to go upstairs and to not touch my stuff anymore? Am I wrong for getting mad about this? I grew up in a house where our personal items, clothes, food, and boundaries were respected but here she has no respect for any of it. She doesn’t knock before coming into our room, she doesn’t ask if she can come down here with us even though we’ve told her multiple times to do so, she leaves her trash all over our bedroom even though we ask her to clean up after herself. I feel bad for getting mad and telling her to go upstairs but should I feel bad for this? Talking to her does absolutely nothing, it’s literally in one ear and out the other. We’ve talked to their parents about it but it does no good because she doesn’t listen to them either.
