Pregnancy

So I’m 21 years old, I have a fwb and we’ve been sleeping together for almost 4 months. Yesterday I found out I was pregnant. He’s 26 never has had a girlfriend and doesn’t want one. I’ve talked to him and he said he wasn’t ready to be a dad and I’m not sure if I’m ready to be a mom. I’ve thought about  terminating the pregnancy and I don’t think I can do that.I do have a good support system but I’m still up in the air about what I want I was just wondering if anyone has had something like this happen to them. - also for a little backstory, I was in a 5 year relationship and had 3 miscarriages and my ex was very toxic, told me i lied for attention or I was trying to trap him. So this is a lot of anxiety for me. Thankfully when I told my fwb he was very nice about it and he hugged me and gave me kisses. He did say whatever happens we’ll figure it out. But like i said he said he wasn’t ready to be a dad and I don’t want to make a decision he’ll hate me for.
