Is this normal?

So my sister recently had a baby and it’s made me think more seriously about what i want in life. I’ve never really wanted a family and marriage but recently i do. I told my boyfriend about this and he expressed to me that he doesn’t want that right now (which i don’t either honestly but down the line i do) and we talked it out and heard each other through, but a part of me is extremely worried that we won’t make it and i need some advice.

I know we’re both in our early early 20’s and i don’t necessarily want all that right now either but he’s said that he wants to figure himself out first before having a family and kids which i honestly do too.

We both agree we want a future together, but as of right now we want different kinds

Has anyone been through anything similar? I have clinical anxiety and this has been stressing me out thinking about the future like this.
