"Love works in mysterious ways, but one of the most perplexing of dating mysteries is how we can suddenly go from intense attraction to intense repulsion when it comes to the same guy." I think we have all experienced this sentiment, be it with someone we're crushing on at work or even a long-term partner. Little things start to bother you that never bothered you before and it turns into full blown disgust. "In the beginning of a relationship, we look for reasons to like someone," says Carrie Cole, a couples therapist in the Houston area. "But if things have started to deteriorate in the relationship, we focus on our partner's bad qualities — it's called negative sentiment override." My advice would be to talk out the issues right when you begin to notice them so that you can both work on accepting each other's faults. Chances are, once you say what is bothering you out loud, you'll realize just how silly you sound!
