I don't see any problem in not being married yet. I have aunts that are way older and never got married not because they did have a chance but bc they say it wasn't for them. On the other hand I've been married since I was 20 (I'm know 24) and everyone's questions is when are we having kids.
I don't want kids for a while (yes hubby is in agreement). I would like to be able to stay home with my children and right now that is not possible so no kids for now. Just bc I'm married doesn't mean I need to have children. And just because you're in ur 30's doesn't mean u need to be married. As long as u are happy with your status and now that later on you won't regret your decision I don't see anything wrong with that. The time will come for you to take that step.
