Crush Sentiment Glitch

I have a save that I've been playing for a while, and it has always had a glitch regarding the "crush" sentiment. In high school, my sim developed a crush whom he then dated. The two are now young adults and have since become enemies and no longer have the "crush" sentiment. However, my sim still gets whims stating he wants to talk to his former crush, even though the sentiment is no longer in the sim's profile and they are now enemies. This happens every time I play with this sim! Has anyone else had this problem?
