My daughter (19) has a friend (18) who needed a place to live due to a toxic home life. I have a camper that I don’t use. I agreed to let her live in it so she can finish high school in May. My son ((21) has a cabin on the other side of my property. Son and friend have just started dating. AITA for thinking this is a really bad idea and my daughter is going to be the one hurt in all of this?
