I don’t want to ruin his life

My bf was initially supportive of this surprise pregnancy but he’s quickly getting cold feet and brought up termination. I’m almost 6 weeks. We’ve been dating for only 9 months and he’s younger than me. I’m 26 and he’ll be 23 next month. I feel weird, we never even notice our age gap, but now the 3.5 year difference is showing itself in this situation. I’m ready, I’ve accepted the pregnancy and I’ve grown to be so happy about it. But he’s afraid and I get it, and I want to take his feelings into consideration. He says he’ll support my decision if I decide to keep our baby but he honestly isn’t ready. I respect him so much but I also love the baby already, and the thought of abortion makes my heart break. I’m so conflicted 😔
