If you were in a committed relationship and a past crush/blast from the past (not an ex, but someone you previously had a significant crush on) happened to make an appearance in your life would you sacrifice your relationship to have a go at it with that past crush?
I guess it depends. How much do I like the person I'm in a relationship with? How much do I like the crush? What are the odds of my getting into a long-term relationship with the crush instead of just a fling? Do I (still?) think the crush would make a good long-term girlfriend? What's the quality of my relationship with my current girlfriend?
If the relationship is going well and I love my girlfriend then I probably wouldn't risk it by getting with the crush. Unless, of course, we had an open relationship.
