I'm not going to argue that the child should not come first, its the only thing that really matters. My argument is this: His wife decided to act the way she has without thinking about the consequences to her husband and her child, This man obviously loves her and his daughter and is willing to sacrifice his home and contact with his child to suit her needs, not his, why should his wife not be the one to make the difficult decision of moving out and managing her life away from the FH as looking at the whole story if they did ever split (which i hope they don't) then she may have to do that anyway and sell the FH as her part time work may not cover the bills etc. So my advice would still be not to move out or let her move out.
