Tired of Being a Married Single Mom

I have officially lost my identity because I have to play all of the roles in the household: protector, provider, cook, housekeeper, nurse, teacher, etc. What’s the point of being married if one person is pulling all of the weight? This man comes and goes as he pleases with no regard for anyone but himself. He puts his own selfish ambitions before anyone and has the nerve to think that he’s being a good father. The conversations I’ve had expressing the way I feel has repeatedly fallen on deaf ears. I do not want to seek therapy/counseling, I just want to be done with this shit. Let me be a single mother in peace!!!
