I want another baby

Mya ❤
I don't know why this feels like such a hard decision. Me and my SO found out I was pregnant in march and a few weeks after I miscarried. I want to try again so bad I want to ask him to try but at the same time I don't. It's not about readiness it's about the fear of losing another one. He has a daughter from his ex and never got the chance to be a dad, and when he found out I was pregnant he got so happy he was gunna be a dad again and was going to be given a second chance. I wanted the chance to be a mom and was so happy to be given that chance and it was taken from both of us. Its really beginning to kill me inside that I feel this way and feel so torn. I want to talk to him so bad but I don't know how to get rid of this feeling. Suggestions :/
