Husband was telling another woman on the phone he wished we weren’t together

I was in the living room and could hear him on the phone. He was talking to some girl. Smiling, laughing and talking about inappropriate stuff like porn.

She knew who I was cuz she said “ I thought you guys weren’t together anymore” really? I told him to shut up after he agreed with here and eventually he told me to kill my self.

I didn’t speak anymore after that but that was crossing the line. I’m 34 weeks pregnant. I don’t need this stress right now.

I don’t even know how to go about discussing this.

What should I do?

I don’t have any where else to go. No car or job. I really rely on him for everything.
