<human>: So when I first started dating my boyfriend we both came to the conclusion that having kids wasn't for us and he has made it extremely clear over the past year and a half that having kids is completely off the table. 

I was okay with that up until a couple weeks ago. I don't know what it was but something switched. I was also watching the Frank Sinatra documentary last night and could only think about how when my parents' time comes, I will have no family and I will be completely alone (aside from my bf and his family). It has been eating away at me and I know if I bring it up, he will immediately dismiss the topic and shoot it down right there. And Btw I'm not planning on having kids until I'm well into my 20's or even early 30's depending on how life treats me.

He has brought up in conversations "if I ever had kids....." And he talks about how he'd raise a kid if he had one. I think it's cause we are both super young, he's still very immature as far as the brain growing and all that. I am honestly not quite sure if or how I should bring this up. This is very important to me and I feel like I'm keeping a huge part of myself from him by not telling him.

Condense the text into a few key points
<bot>: having second thoughts about not having kids for fear of being alone when my parents die and I'm not sure how to bring it up to by extremely opinionated boyfriend.
