<human>: A little backstory; my ex asked to end things between us after 1 year because he didn't  feel the same anymore. We decided to keep in contact and not delete each other off social networks, which was fine for me at first but after two months I couldn't handle having him in my network but not being able to talk to him, even worst, seeing his life move on without me being in it. I stopped using all social media but accidentally went on instagram and saw his photos today, after a few weeks of not going on it. He was totally fine and seemed to be having so much fun with his colleagues (female ones).  I broke down and started crying again because i miss him terribly. 

I know it's over and it's no good for me to dwell on this negative feeling. But I'm still not over him and I don't know what i need to do to feel better.

Condense the text into a few key points
<bot>: Ended things with ex on a good note, but I'm not handling having him in my life and not being able to talk, well.
