Based on a very long thread on another site, I've been thinking about people who cheat in relationships.

My opinion is that one strike and you're done. Hubs and I have never been in a relationship with anybody else, and we've had to really make sure that we have learned both how to be in a relationship and how to be in a relationship with each other. I don't see either of us as the cheating type, but we have discussed how we'd feel.
What's your take on cheating? If your SO cheated or told you that they had cheated in the past, what would you do? Would it be different if it was pre or post kids?
