You might change your mind

So I've been talking to this guy for a bit. We live in different states and were just texting each other. He brought up having a baby and asked if I wanted kids and I said no and he asked why not. I basically said I'm cool without having kids and I asked if he want some and he said yeah. I told him we should just end this now cuz I've dealt with this situation before. I told him if he wants kids than he'll still want them at some point. He said I might change my mind just like he might change his mind smh. I'm 37 and I think he's about 46 with kids. Like dude if you want kids and wanna find someone stable enough that wants that same thing than that'll be cool but why would you wanna have a kid at that big age and by the time you possibly have one, you'll be in your 50s. I really did like him but saying I'll probably change my mind is just ugh. With the way this economy is right now, there's no way in hell I'd wanna have a kid.
