So what makes you think YOU are doing something wrong? I'm confused on that issue...

Speaking from experience, and I've had some... all told I've been married for 41 yrs of my 63... and if your gf isn't as emotionally responsive as you are, you'll be going down a very frustrating road.

Sounds to me like you're more than ready to make a commitment, but she's not.

I've had long distance relationships. They don't always work out to our liking... especially when the other isn't as emotionally commited as we are.

You have a lot of thinking and talking to go through, I think, before you make a decision. Good luck!
