I dated this guy for a few month but it was super intense.He broke up with me out of the blue , sending me a text and telling me that our relationship has been rocky and we might not be the best long term fit for each other.I felt really bad the first couple of days but after that I came back to my normal life.Today I find myself missing him , I know I won't see him anymore and I even cried , it has been two weeks since we broke up. What can I do to move on and don't even think about him.
