I've been dating a girl for 3-ish years now. She's a great girl (AWALT and all, she really is). I don't have too many complaints. I'd say I'm happy or at least content in the relationship. In short, nothing is really, critically wrong.

However... as time goes on I'm realizing I'm not ready to settle down yet. I'm not ready for marriage. In her mind, I'm sure we get closer to being "together forever" each passing day. In my mind half of me loves her, half of me is ready to do something new, see new people, etc.

In short, I'm in a good relationship but I'm not ready for marriage or to settle down for good. I don't know what to really do here. I've been contemplating having a talk with her about this but I'm not exactly sure how to talk about it. In some ways I don't even know what I think about this.

I was wondering if any of you all had some experiences to share on this or advice to give. Much appreciated.
