Rushing good things?

So my boyfriend and I have known each other for 2 years and recently started dating like 6 months ago, he’s divorced and has a child with a completely different woman (not me or the ex wife). He’s a very active father and I love his daughter but I would also like kids of my own, to get married and blah blah, there’s a decent age gap between us, me being 22 and him being 27 and obviously our experiences are different due to his prior relationships but I’m very much so ready for the future, never really been into party. Everyone says live out your 20s but it’s just not my thing… Every time I bring these things up he gets quiet and doesn’t have much to say. Other than this we’re always on the same page and things have always been great between us. I guess I’m just nervous he doesn’t want another kid or to get married and I’m not really sure where to go from here… open to anything at this point.
