I have been having a hard time getting over my ex. I constantly think about him and I want it to stop. I find myself trying to look up anything on social media or sites I know he used in the past just to get/see any information(even though it breaks my heart to find anything).

Things ended badly and there really was no reason/explanation/closure on his end. He would often just shut down and it is like holding a conversation with a brick wall.
Although only confirmed by his actions I came to realize he really did not care about me or love me like he said he did I am having the hardest time letting go.

It is all I can think about and I just wish I could erase him from my memory.
Any suggestions on how I can stop this behavior? When I wake up I am checking/thinking about him, at work then when I get home from work
