Does anyone else associate a bad memory with something and then have a "grudge" against that thing for a while?

When I was a freshman, Boyrax and I broke up for a week or so. The last thing I had written on his Facebook wall was a line to a song. The song and the breakup were unrelated entirely, but for over a year after I just didn't listen to the song because it made me all sad and stuff. I do this all the time and it makes me feel kinda crazy. Am I the only one?
