Cheating Husband Pregnant w/ 2 babies at home

I caught my husband cheating last week . It completely blindsided me as I thought we were both happy... a power couple that could take on the world. You know? I immediately filed a petition for divorce and custody. I was determined that I was going to woman up and raise our almost three year old and 15 month old on my own. Then yesterday... I went to the doctor to get tested for stds to make sure he hadn’t exposed me to anything and discovered that my lingering suspicion for the last week was correct. I’m pregnant . IDK what to even do. Divorce. pregnancy. Two small kids. Classes. Work... I feel like I can’t do this.

He’s asked to come back but he’s made it very clear he doesn’t want me to keep the new baby so long as the divorce judgement is still in effect. What do you think?
