My new Boyfriend found out his ex is pregnant. I'm devastated and any encouragement is welcome

I met Ahmed around New Years. We were amazing together and we hit it off. He was raised in a very conservative Muslim family, and when he tried to talk to his parents about me, it didn't go well. I fell for him fast anyway, and we were happy. I'm 22 and I'd never been in a relationship before, so I was really excited about all of this. We were very serious, and we were taking it slow, and making plans. 
Then yesterday happened. A week before he met me he met up with one of his exes and they had sex. She told him yesterday that she is pregnant. He's really upset, and he takes full responsibility for it. I can't stop crying. Of course he's getting back together with her, and I want him to, because it's the right thing to do. I'm upset with him because Even though we hadn't had sex, we talked about it and  he told me he hates using condoms, and I told him it was non negotiable. 
Their first OB appointment is tomorrow, where they will find out 100% whether she's pregnant or not, but there's no way she isn't. Every home test was positive. 
We were supposed to get together today to say goodbye to each other, but he's having to work a lot today, and I'm trying really hard not to text him and bother him. 
I haven't gotten out of bed since I found out last night, and I just need some wisdom and encouragement from you guys. I can't stop crying.
