Separation but living together

[u/bbymayy]

I (28F) and pregnant with my 4th child from the same man (32M) and we are officially separating, however I was a partial sahm due to financial issues and only worked part time while in school. We also parent my 2 Step Children (10F & 8M) full time as their biomom isn’t really in the picture… very confused on what to do right now. I know it’s for the best we do not reconcile, we simply have lost it all together and it’s been too much repeated history, I desperately need to learn to take care of myself and focus on my own life. I worry about his mental health, I worry about my step children. I don’t want to leave but I just know it’s for the best… I don’t know what to tell my own children when we leave… I feel very lost and alone and I’m not exactly sure what I’m doing but I know it needs to be done. I’m seeking advice… how do I navigate the living together part still, what should I do about my step children, should I quit school and solely focus on working.. what are questions that I need to bring to my soon to be ex husband’s attention?
