Do I hang on? Financial Woes w/Hubby?

My husband owns his own business and lately business is bad and the checks are further and further apart. This led me to having to go back to work and not be able to stay home with my 1 yr old who I adore. He resolved himself to the fact that he has to get a fulltime job to help out more with the family bills because lately I feel like I pay for everything. He has a good resume and has been on a million interviews. he is starting to get discouraged and so aren't I. I dont know wether I can keep sticking by him or if I should leave just for my own financial safety and well being. I t has been over a year now of barely making ends meet and it is totally effecting our relationship, we tried counseling but didnt work. The only thing is that he is the best dad in the world. I dont know what to do, am I being a bad wife or should I leave him??
