hey man that's good to hear that you will be going out with a girl 30 minutes away. 30 minutes isn't bad at all!
well your issue lies in that 2 months and your gone. Hopefully the girl knows that so both of you can plan accordingly if you 2 get serious of course.

Maybe this girl is a hole to plug up your sadness, maybe she isn't. Cherish what precious little time you have with a girl who is willing to give up time for you. If it doesn't work out, you can always be her friend, a shoulder to lean on.

You're obviously not completely over your ex but there is no real rush. let it gradually grow away, but from experience after finding someone new whether i wanted to heal the sadness, it made me really forget the pain involved with my ex. Girls come and go, and there is no way you can take what happened in the past and change it. Just keep living and moving on with a smile on your face rather than a worried frown about a lost past.
