There are times when two people find a strong mutual attraction between them, and they choose to form a relationship. It might go well for the first few months, but small things can begin to get in their way as time passes. They could believe they can work past all their issues, but more keep creeping into their lives. When it does not work, life with the other person can become unbearable for both of them.
It might look from the outside as if the two should simply call it quits, but many people are amazed to realize they will continue trying to regain their former relationship for quite a while. Some of them will be unwilling to give up the effort to capture their former attraction, and others might have fallen too deeply in love. While it would make sense for the two to part company, the consequences to each of them might be what holds them together.
