I have a daughter in Ont who moved there two years ago with here son to be with her boyfriend. The relationship with him was shaking with her finding out that he was having an affair with an old girlfriend last summer. He appologized and they sought counselling. Against my advice they bought a house in Toronto in Nov 09 and recently he told her that he can't continue the relationship. They both signed the mortgage although he has made the payments and she has bought the food etc. My daughter is in a real pickle, with a son in school and he wants her to move out. With her income alone, she couldn't even afford a one bedroom apartment. Then there is moving her son out of school. He is in his second school in two years. The best option is for her to stay in the house. Does 'he' have responsibilities since they have only be 'common lawish' for two years?
