I was dating this guy, which I left him years ago because he was broke, not that I don’t love him.

He later traveled out after four years, and we started talking again. He told me he would like to marry me, but I have to get pregnant for him first.
I agreed and asked him to come back so we can do the do for me to get pregnant. He said I should look for someone that would do that.

That he just wants to be sure that I’m fertile,
that once I get pregnant, he will come back and claim the child, marry me and take me abroad with him.
I agreed and I had a one-night stand with a guy I don’t even know. I found out I’m pregnant, and I notified him. He sounded excited, telling me that he will come back when I’m seven months gone. So I can give birth abroad when we travel together.

It’s seven months now, and I’ve asked him how about the plan. He said that I have never changed , that how do I expect him to take another man’s child?
He told me it’s a payback for me for leaving him when he had 😭😭😭I’m confused. What should I do?
