Is It Wrong For A Man To Live In His Family House?

Hi guys. need your advice please. this thing is baffling my mind badly.
everyone know how bad and poor Nigeria economy it is. saying no money here and there . am living in family house, face me and slap you . my dad is late but my mum struggle to build the house and she also live there too. the problem now is that my gf is threatening me to go and rent room and parlour outside Cos she wants to settle down soon but I got no money with me now. infact am on sick bed for the past two months and I can't work for now. am just a hustler, trying to make life good and comfortable for myself. and I love this girl like die. she's house materials but this house issues is the only problem am having with her, meanwhile am using room and parlour in this my mum house o. (even is not my happiness to be living in family house too )but no money for now. she's also disturbing me for engagement too inwhich I will be responsible for all the expenses because she's still learning handwork. though age is not on her side but I love her so very much that I can't afford to loose her to another man.
the question now is........... IS IT TOTALLY WRONG FOR MEN TO BE LIVING IN FAMILY HOUSE WITH HIS WIFE.
