Pregnant and abandoned!

I'm a pregnant woman, and my mother-in-law kicked me out of the house, cursing at me in the street while my husband just stood there silently. I went to stay at my family's house, and he later tried to convince me to move back in. I told him I wouldn't live with his family anymore; if he wanted to save our marriage, he needed to arrange separate accommodation for us and our baby. He led me on, taking me to property viewings, only to later reveal he had no intention of getting separate accommodation. He threatened me, saying that if I wouldn’t live with him and his family, he would divorce me. After that, I cut off contact with him. I've been going through my entire pregnancy alone, buying everything for our baby myself—he hasn't contributed a single penny. Now, with the baby arriving in 4-5 weeks, he's been trying to reach out to me. He refuses to acknowledge his mother's wrongdoings and keeps defending her. I absolutely refuse to let my child be around that toxic, narcissistic woman. To make matters worse, he’s been talking to other women while still being married to me, even sharing intimate videos of us. This is not the life I want for my child!
