I have a problem. My girlfriend just told me today that she had kissed another guy but only for one second. The problem is that it happened a couple of weeks ago and she just told me. I don't know what to do. I love her and it's been going very well so far, but right now I am just mad. I don't want to break up. Please help me be a man of God, please.
A question I have that you can't answer is: why did she tell you? She could have brushed off as something that didn't matter because she didn't see anything wrong with flirting with multiple guys. She could have said it didn't mean anything to her -- that she was just being nice to a guy who was feeling sad. But instead she told you something that you would have have suspected. It could be because of guilt or it could be because she was trying to provoke you. What I'm getting at is that what she did is not nearly as important as why she did it and told you about it.
Dating is the time to get to know someone well before you decide if you want to marry that person. You've just been handed a clue about an aspect to her personality that you did not suspect. Rather than making a quick decision, I think this calls for slowing any decisions down until you see if there is a pattern to her behavior.
