I'm 28 and have been with my wife for over 11 and a half years now, we just got married 2 years ago. I felt kinda nervous, but I loved the woman and thought that nothing could go wrong since we've already been through just about everything that a couple could go through going through our 16-28 years of our lives. If we survived those years, then there must be something here, ha ha ha.
It's not bad being married, it's actually good. As with everything, it has it's ups and downs. Once you start having a few kids, you'll be doing fine
It's just hard to believe that I have 3 kids, I never picture myself like that, he he he.
I have a couple of buddies that are 29 and they don't even have a stable woman in their life. They'd love to be in my shoes with a full family. Go for the wife while you can
