<human>: Can you give me a shortened version of the text?

For starters (throw away) I'm 23 and she's 21 and it was a year and half relationship. Both of us where very happy and thoroughly enjoyed each others company.

I was recently picked up for a great career building job but it was over 600 miles away from where I was currently living. This included me leaving all of my friends, family, and of course my ex. After some discussion my ex and I decided that it would be best for a split because of the uncertainty with long distance relationships and we both wouldn't have the funds to make regular trips out to see each other. 

We recently went on a trip with some mutual friends and it was incredibly awkward. Up until this point she had been treating the after math very crudely, by that I mean some days she would acknowledge her feelings and other days she would be strictly platonic. Though we had both agreed to be friends, she was taking this to the extreme and essentially avoided the entire situation and me during the trip until I confronted her. After some much needed discussion we decided it would be best that after the trip that we kept contact to an absolute bear minimum for both of our sakes. 

I've tried online dating and other things in order to kinda start moving forward. I've been on a few and tried my luck with other women but nothing substantial has come up. I still find myself wanting to talk to her and try and be close to her. This may be due to the fact that my relationship with my ex has been the best yet. 

Is there anything else I can do in order get over this overwhelming compulsion to want to still be close to her? Am I acting selfish because I thought it was such a great relationship?
<bot>: Moved to another state for a great job but can't stop thinking about my ex. Is there anything I can do to moved forward?
