My son father putting me through hell when I’m 5 days away from deliver

I am currently unemployed due to covid but before that to I was working like crazy trying to keep the home up for my 6 year old son and his 1year old son. He all of sudden now mad at the fact that I am not working and waiting on my unemployment. He did 32hours of overtime last week just so that he can cut everything off in our home and move out while I’m 5 days away from delivery. I’ve cried non stop for past few days about this situation, and he stated to a mutual friend that he’s doing all this so that he will get full custody of our son, that if I wanted peace and not have him come to our home and make scenes for neighbor he would give me joint custody. I have full custody of my 6yr old and I’ve always worked hard to provide for my sons but him expecting me to get straight back to work after the baby without taking maternity leave so that he can go back to sending money to his mom in Nigeria is ridiculous and causing this much stress on me in hopes of me having a melt down is beyond words. He fails to realize when it comes to mother and they babies is like a bear and it’s cubs. I’m so hurt but trying to remain strong
