I'm really confused but I'm sure I don't want a sixth abortion

I'm 19, going to be 20 soon. A Nigerian and a muslim. I've had 5 abortions since 2011.

A few months ago, I decided to practice my religion more because I felt it's the right thing to do. I thought I was becoming a better person.

I met this man who asked me to marry him... he's married already but has some issues with his wife. Because he's a muslim, he can marry more than one wife.

Though I had a boyfriend who loved me, and still does, I decided to marry the other man because I believed he could help me become a better Muslim as I thought he was one himself.

One thing led to another, I fell in love with him, and now I'm pregnant.

I know keeping this baby will change a lot in my life and there are a lot of things at stake but he wants me to have an abortion because he thinks people finding out I'm pregnant for him out of wedlock is going to tarnish his image and his life might be ruined.

I don't know what to do... I don't wanna be responsible for ruining his life and I don't wanna have an abortion.

I explained my situation to my ex boyfriend whom I left him for and he said if I really wanna have the kid, he's gonna be responsible for it.

I'm really confused and don't know what to do but one thing I'm sure of is I don't want a sixth abortion.
