We were only together for a few months, but knew each other longer. I know logically that it’s ridiculous to be hung up on someone I spent such a short period of my life with, but I really cannot stop it 
I know it sounds cheesy, but I have truly never felt this way about anyone before - I have had past long term relationships, but nothing matched this.
The ending was shit and completely lacked closure. I’m sure there were things which I could have done differently too, but the bottom line is I am stuck in a horrible limbo, feeling unable to move on or let go because I haven’t felt this before ever for someone. 
What do I do, how do I get over him?
Desperately need some advice please
