<human>: Can you provide a brief overview of the text?

For the past 6 months, I have been dating girl 1. She's an amazing girl, treats me better than I truly deserve, and I really do love her. The only issue with our relationship is that we don't see eye-to-eye about marriage and kids; things that would make a long term thing difficult.

I've known girl 2 for nine years now. We are incredibly close and I've had the biggest crush on her for pretty much the entire time I've known her. Unfortunately, we've never been single at the same time so nothing's ever happened. I never even thought she was interested in me until recently.

I was hanging out with girl 2 and a handful of other friends after work one night. This is a regular thing that we do so nothing seemed peculiar. We were all drinking and playing cards. Everyone besides girl 2 and me got up to leave at once. I was helping pick up like usual when she kissed me without warning. Obviously I declined immediately and went home. The issue with this is that I can't stop thinking about her now. All of these old feelings have resurfaced, but I also love girl 1. I don't want to physically or emotionally cheat on anyone since I'm incredibly loyal, but I have no idea what to do. 

I'm not sure what I'm really asking for here, but I'm hoping maybe someone can help me put my jumbled mind at ease with some advice.
<bot>: already in a relationship, old friend kissed me, I have feelings for old friend and can't stop thinking about her despite still loving my current girlfriend.
