He doesn’t want kids

So when I first met my boyfriend, he seemed to love kids. He made a few statements about being a dad. I was almost scared lol. But yesterday he said he doesn’t want kids and was talking about a vasectomy. He said he doesn’t want to bring a child into this world and that he doesn’t want to pass his health problems along. He’s only 21! I was a little conflicted but then I figured he wasn’t sure yet. I mean 3 months ago he wanted kids. I’m not completely sure what I want but it’s weird to think I might not get that chance

I love my nieces and nephews. But when they’re being bad, I can’t deal. Plus babies kinda scare me

To get his mind off of a vasectomy, I said something about getting an IUD.
