My husband won't just work,I have been paying bills for the house for 4yrs now,I am now fed up;i can't take it anymore.Anytime this issue comes up we always fight. He claims he is trying but I can't see that in his attitude,I think he is taking me forgranted.

Yeah sounds like free ride & free meal ticket

Has he become a house-husband? What does he do instead of working?

You are being taken for a ride if he can't find work in 4 years. Apparently he is not trying hard enough. There are jobs out there if a person is motivated enough to find them. What did he do prior to your marriage and how did he become jobless?
