I dont want him anymore

Talking about my BD. I've done child rearing alone for the most part.however he's just NOW I mean like 2wks ago now just helping.

He's doing a good job; he watches the kids while I'm at work over night,cleans and feeds them even now he's washing laundry.

How ever, when our daughter was little basically newborn to 3 ( now) I had to take care of her while he was 15mins away. I did it all while dealing with toxic parents. I got her walking, potty trained able to feed herself.

Then when he did live with me for a little while he was looking at escorts in bed next to me bc he said he wasn't getting enough attention. Then tried to lie about it then said , " I'm a man-- what am I supposed to do? Look at boys?!" ( hes also called me a whore and hit me with my pants)

Then when I tried to move on he kept sending flirty texts and would not stop and the relationship ended.

I'm glad he's helping me bc my family is toxic and he's the only one I have to watch the kids so I can work but he keeps asking me to marry him and I simply don't want to bc he ruined and sabatoaged a chance I had at a decent relationship just so I could be with him. No.

I keep telling him it's over but when I need his help and he has to stay with me it gives him hope. Even his mother said she was glad me and him were working things out.

I just don't want him and I've told him this plain as day multiple times. He still lives in a delusion that were together. I appreciate his help but I don't want him.

Idk what to do. Even though he'd helping its 4yrs too late. I can't reboot romantic feelings for him. I can't@ realist: he is on child support. He hasnt paid in the last 3vmonths. Baby sitters cost more money than i make at the moment. I would need a super cheap one.
