<human>: I've been with my girlfriend for 3 years, we can call her Amanda.. 
Amanda is a great person and an amazing friend to me. She is very trustworthy and genuine, however there are some things pushing me away from being with her longer. 

Before I dated Amanda, I had one other girlfriend, we can call her Emily. Emily was my first love but we broke up after senior year in high school. 3 weeks after we broke up I met Amanda and started dating her. It was way too soon for me as I still was in love with Emily. But I got over her and after a while fell in love with Amanda. 

Starting last year I started talking to Emily and we made a new friendship. Emily and I click together better than me and Amanda which kills me because of how much Amanda cares for me. I just don't feel as strongly for her.. she wants to get married to me and I already know I don't. I've tried breaking up with her but she always stays and never gives up on me.. which makes me want to stay. 

So fast forward to how I messed up. Amanda has been gone on vacation to her relatives place, and last night Emily wanted to hang out. I went to her house and after a few laughs and playful gestures we kiss. It was the most amazing kiss I've had in years. I kiss her everywhere and we can't let go of each other. I think she wanted to take it further but I couldn't, but we kept cuddling. We were so happy to be there together and I haven't felt a connection like that in years. I feel like poop and I don't know what to do from here.. should I just move on from that and be better to Amanda? I'm lost.

Can you provide a brief rundown of the text in within 3 sentences?
