Please help with advice 😭

So I was picking out wedding rings and trying for a baby with my partner. It was the best relationship of my entire life. I was so happy. My kids loved him. Then I found out he was cheating on me with at least 5 women with sexting and getting girls numbers at the grocery store. I don’t have proof if he actually slept with them while we were together or if it was just messaging but regardless it was heartbreaking. I broke up with him, and a couple weeks later I slept with my friend. I know bad decision and I regret it so much but at the time I was so broken and hurting. Well found out I’m pregnant and I told my ex and he told me to have an abortion since it’s probably the friends. I said no. Now I’m 8 weeks and he just called me saying he loves me so much and wants to have a future with me but that I need to have an abortion cuz he can’t stand seeing the woman he loves pregnant with another man’s child. I’m crying cuz I love him but can’t believe he would ask me to get an abortion. I am prepared to do this on my own but that phone call wrecked me. Can anyone please please give me advice ?
