Part time?

Have you ever decided that you don’t want to be a full time parent anymore just because you can’t take it? My children’s father has gotten so lazy and I feel like he’s using me as a crutch. He no longer helps me take care of the babies the way he’s suppose to and PPD is hitting so strong right now. I am attending therapy but even during therapy they’re always whining or crying. I can’t do anything without hearing them fry while he has them. I can’t even do basic necessities when I need to because I’m so busy with the kids. I now want to move out and get my own space so that I can split parenting time versus being a full time mom 25/8. I feel a bit guilty about it but mentally I want to take care of myself too because my children deserve the best version of me.
