I don't know how to resolve it. Any suggestions for getting over someone?
To quote my favorite movie
The Shawshank Redemption, "in prison a man will do most anything to keep his mind occupied". The background of that part of the movie is that one of the characters escaped from the prison (don't worry, he was innocent) after digging a secret tunnel through the wall which took him twenty years.
The demons like to build prisons around us. You've had one built around you from this breakup and you probably feel pretty down in the dumps too (it's a breakup it happens). Find something to do! Keep your mind off of it! Find something that you don't think you'd ever do out of fear and conquer it.
I lived in California for a year and a half. Roughly a year into it there was a girl I had a bit of a crush on and when I finally asked her out I got rejected. I felt like crap. I had always wanted to go skydiving and decided that if I could actually jump out of the plane than I could get over this (the crush lasted a long time, okay?) and I did.
When I was leaving California for Mississippi to do some training with the Navy, and there was a different woman whom I had been on a few dates with and thought she was perfect and I wanted to continue the relationship long-distance style. She didn't, and didn't tell me until I was right inside the Arizona desert (yes, I was driving the whole way) via text message. I spent the entire drive from Arizona to Texas a bit depressed and ticked off, but I also spent it immersing myself into my surroundings on the road while listening to some 90s rock. I spent that bit of my drive in a state of almost-meditation levels of contemplation and by the time I got to Texas two days later, I was no longer mad about it.
So, breakups suck especially those ones with people whom we weren't in a relationship with who we thought we perfect in our eyes. Like any other breakup, I've found that the best things to do are to keep your mind off of them (and the breakup) and to do something to boost your confidence. For me it was skydiving and absorbing the desert as I drove across the country by myself. You need to find something to boost your confidence.
