Tonight, my girlfriend let it slip that she used to sleep with someone who she knew was in a relationship.

Apparently, she was pressured into it, and it happened over the span of a few years.

She claims that although it wasn't right, she claims that she wasn't being dishonest, and she claims that she would never cheat in a relationship. She says she felt it wasn't her responsibility, that she still didn't feel good about it, but that it doesn't mean that I can't trust her.

She asserts the fact that she has never cheated in her past (2) relationships, and she asserts that this is much different then cheating, and that I cannot compare the two.

I'm on the verge of dumping her? Am I jumping the gun here? Am I overreacting? I can't even tell. I had a very choppy childhood, so I can't even tell with this shit.
