A Strange Mental connection.

For my entire 17 year life I have been a supporter of Chelsea Football Club. Recently however, I made a mental connection between them and my former crush- who turned out to be a really horrible person who betrayed numerous amounts of people including myself. 

This has resulted in me losing the passion and enthusiasm for supporting the team. I don't know why its happened, or why I made the mental connection between the 2 in the first place. Does anyone else reading this know what I'm going through? Has anyone else evr made a mental conncetion between something you love something you hate, causing you to lose the thing you loved? Or has someone successfully managed to solve this problem? 

If so, could you give me an in depth explanation on how you did it? If not, could anyone give me an idea on how I could solve it? I have been unable to find help anywhere else. 

Feedback would be apprectiated. Thank you very much.
