It happened a few times. I just kept believing her, I feel stupid for believing her so many times. But I will tell you one thing it was ridiculously hard trusting her. If you have even the littlest feeling that you're going to have trouble trusting her it's just going to get harder. It will eat away at you and will drive you crazy.
Turned out she was cheating.
okay, now, i'm in my situation, so maybe this is a defensive mechanism on my part but, for me i'm seeing a key difference in my situation, and this one. from what i'm reading, your gf minimized it, and wrote it off as just being friendly. mine has acknowledged that what she was doing was wrong, and owned up to it. yes, she tried to claim the message dates were inaccurate at first but, she did own up to it, and didn't just write it off as being "friendly".
i appreciate your feedback. but, i'm just not sure how much of an apples to apples comparison this is.
