Ladies! Moving in with my SO!

My SO and I have decided to move in together. I'm so excited, but scared at the same time. I'm moving out of my parent's house (I'm 22) and into his apartment. I want to live with him more than anything in the world and I know it's a good decision for us. But there is a tiny part of me that worries maybe one day I'll regret never living on my own, even though I've heard from friends being alone is not all its cracked up to be. What was your personal experience with moving in with your SO? Did you live on your own first? And if you didnt, do you regret that you never did?
