My 21 year old son lives away from home at uni, his father and i are no longer together. I have a partner of 6 years and we live separately. He would like me and my younger daughter to move in with him, financially we would both be better off, however there is no room for my older son who lives at uni. Do you think its unfair to give up my house and move in with my partner when there is no room for my son? He has a bedroom at his dads house which is 10 mins away from mine so he has soemwhere to stay when he comes home.
