Would you stay in the relationship even you're not happy just for the kids?

I am on the same situation, i guess. My husband and i do not agree in terms of how he manage his finances (because i shoulder our expenses, and all of his salary is directly given only to his mom), how he gives much of his time for his parents and siblings, his group of friends, his workmates leaving us feel unprioritized and unloved. I am married to an immature-happy go lucky-irresponsible man. What should i do? Pls help.
