How much time before the real commitment?

I'm 28 and I'm in a relationship with a boy 2 years younger than me. We've been together for 3 months and I start asking myself if this thing goes in the right direction - for me... It's the beginning but I tend to feel like a teenager just going out with someone like in high school... I want a real thing, and he still chooses his family over me, he passes his weekends with them and if he stays with me, he doesn't suggest going somewhere, like travel or anything, we just go to the movies, eat outside or stay home. All my friends in my age are married or in long relationships and they tell me that I should give him a month and not more than that, to see if he has some more projects with me or is it just childish hanging out. I wanna have a family, kids, etc. Of course, not after 3 months, but maybe I'm just loosing my time with this guy, cause he'll want that like in 10 years...

So... how much time should I wait?

I know that probably everybody will say: there's no rule, it just happens when you're ready, etc; etc. But still, I'd like to know your opinion because I don't have much experience, have only been in a relationship once, and that went TOO fast: we started living together after 3 months of dating and before we were seeing each other 2 times a month, that was a bit crazy... What d'u think?
