Wanting to settle down

I'm 27 and I've been with this guy 7 months. As I'm getting older I really want to settle down and have a baby, a nice family. Stuff like that. Maybe 7 months is too soon, but I'm not getting any younger. My boyfriend is what you would call a "party boy". He goes out every weekend to drink. He's always posting pictures on Instagram of him playing beer pong, taking shots, etc. He just barely turned 22 so I get he's a bit younger than I am and is at that stage in life. I'm just sad because honestly I want a family now...
