I need some perspective as I feel like I'm loosing it... DS (20)is in Uni. He met a girl online a few weeks ago, they clicked and he traveled to meet her, and almost straight after she came to visit him in Uni and stayed at his room. It's against the Uni housing regulations, but I think as it was the end of the year, it somehow went unnoticed. He came back home a few days ago for the summer, and told us she is coming with him. She is not working or studying and live on UC. It seems she has some family issues. We were always very open and happy to host our kids friends, and very flexible about that, but in this case I feel this is too much, and this girl is taking advantage. For context we are in a middle of a renovation project, and due to delays, our house is a building site, kitchen is half working, currently just one shower , no floor etc. there is also some financial stress and our budget is limited. I'm in perimenapose and my patience level in the current state of things is basically zero. This girl have been here almost a week, she is not once thanked us, or offered to help, buy food etc. Not even doing the dishes, or taking her cup to the sink. They spand the day watching tv, going around , and go to sleep late. We have younger kids, and we both work full-time, so this is disturbing. My husband thinks I'm too harsh, but I think she is taking advantage of the situation. We already ask that she will leave at the end of the week, but I'm afraid she might come back during the summer for long periods, and I'm totally not happy about that. I know I sound like the wicked MIL, but I have no clue what my son finds in her, she is not even trying to connect or be nice to us. We also expect our son to work during the summer, as he needs to save for next year. AIBU not wanting her to live with us during the summer?
