dont feel badly! everyone else is probably jealous that you're still free.
We're in the same boat.. my other half, we are not officially married, (although we might as well be, and we refer to each other as husband and wife to people who dont know us, just to spare the inquirer the explanation) and we do not have kids.. Neither is important to us, and neither is something we're striving for.. We're happy how we are... and people seem to go CRAZY because of this! Im 29, hes 30.. we should be married! We should be settled down! We should have 2 kids by now! Nope.. We'll go at our own pace, thanks
dont feel badly.. be happy that you still can make decisions by yourself, and if you so choose, you can start looking for someone to settle down (or not settle down!) with! Have fun with it.
