Is this weird?

Cassie

I’ve been dating a guy for 6 months and things are going pretty fast I would say we’re seriously dating. He has two children and is a full time father (he has them through the week, the mom has them on weekends) and I don’t have any children. For backstory I’m 26, he’s 33! The other day when I called him his daughter answered the phone and asked me am I gonna be her new mommy!!! (she’s 6) That scared me and now I wanna run 😩 I can’t imagine my life as a mom at this moment .. Am I wrong for feeling like this?? I really like him but that made me so uncomfortable I wanted to hang up the phone. He thought it was funny and cute 🤦🏽‍♀️
