My ex and I got divorced but still live together...advice?re

Single moms how are you doing it? My ex husband and I got divorced and have been living together for 2 months since the divorce was finalized but it’s been so horrible. I go to college full time and work weekends and if I kicked him out I’d have to work full time just to afford the bills on top of going to school full time and I don’t even know who or how I would find someone to watch my kids let alone pay for daycare. I feel like I have no options but me and my children are miserable. Any tips tricks things you did to make it through a similar situation.
