I am renting a property. I let my child's father live with me to get himself together. It has been months; it looks like he is getting comfortable and not looking to move on. We do not get along, I just didn't want to see him on the streets, but the stress is getting to me and I have asked him to leave multiple times. He says he is not going anywhere or if he does then we are both going to have to move. What should I do?
