Once I was in a LDR, and my girlfriend asked if I'd be interested in an open relationship. Then suddenly that same day my crush developed on this woman I've seen all week and kept running in to her everywhere around town. But I didn't act on it.

If you have a crush on someone else other than your partner, get out of the relationship.
That's not fair on your partner.
If it's like a celebrity crush, then that's fine but don't obsess excessively infront of your partner.
