<human>: Pretty sick of my (27m) relationship. My partner (27f) is someone I no longer love.

The only reason why I haven't left yet (and still have second thoughts over) is her child (6f). When I got into this relationship with her things were rocky from the start. But after a year and 1/2 she moved in with me with her daughter. Let me just say that I think her daughter is awesome. I love him so much. But I can't stand any more of her twisted controlling anger.

There are lots of fights now about things I thought would ether be a big deal (Like her swearing at her child when she hit her mother for teasing her, which I could never justify) or her swearing at me if I make a simple mistake (like leaving curtains open in the bed room when I fall asleep).

I've been told that I do nothing (or very little) around the home. Though I KNOW that I do (Pickup her child from school, dishes, bring in washing, pay all the rent and power). So I just feel abused now and being taken advantage of.

The problem I have now is that she is only working part time and I feel as though I can't break up with her because I know it would be horrible for her child and I'm not even sure if she would be able to support herself working part time.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Partner works part time and has a child. I don't know how (or if I should) I can break up with her because I'm worried she would be able to support herself.
