Husband's financial support to Wife in Islam

I have been married for 7 years, and I work on my own, while my wife takes care of our child. Every time I get my salary, I always give 100% of it to my wife. When I get a freelance project, I also always give the earnings to my wife. However, I have debts that may exceed my salary, and my wife tells me that I am stingy and irresponsible as a husband. When I really have nothing, I ask my mother for money and give it to her. Almost every day, I ask my mother for household expenses. If my mother can't provide, I am seen as unable to make an effort. Am I really not providing financially in a case like this?
