I need advice bad :(

On week days and his on weekends and in the summer he wants 50/50 with his kids. I want that too until I realized wow I'm going to be taking care of 7 kids, pregnant, by myself! He has maybe 1 day off a week

To help me... I'm high risk pregnancy...He is a great man, kind caring and financially stable but I'm doing all the housework, and taking care of the kids full time while he works. I have a vehicle I am

Stick with due to a second lien that doesn't fit all of us and with 7 kids it's tight to get another vehicle....our other family members couldn't foster the kids because of past violations and failed drug tests... The day we got them our family begged us to keep the kids so they didn't go into the system so I felt it was our only choice... We may have them for years to come. He promised to step up with helping me around the house and I feel like when I clean the kids just destroy what I've done and I feel really ignored by everyone... I just feel lost and alone, I feel like this is a lot for any marriage let alone a fresh one. I'm so thankful for these kids and our baby to be but I'm so stressed out and I also feel like I can't take care of me... Sorry for my whiny rant. I just need help sorting this out! I've told him all this tonight he just shut down..
