<human>: Reddit, 
This time last week, on a night out at university, a girl in our social group (lets call her DG) told me she had feelings for me, and that if I was single she'd want me. 
Back story, known DG around a year and a half, she's really sweet, been a great friend and is hot as hell, like smoking hot. She came to Uni with a boyfriend so we became friends, one night while we were both single she told me she was attracted to me, I put it down to alcohol, other than socially acceptable flirting, nothing ever happened. 

Fast forward to now, I'm in my first relationship, with a girl I'm  genuinely in love with who lives a couple of hours away. 

But on this night out DG told me she liked me, and had done since she'd met me, but the time had never been right to tell me, why she chose this time I have no idea, but I can't lie, I will say I was curious to hear more. 

Me and a few friends ended up crashing at this girls (fully clothed, for the record), and I slept next to DG. She was teasing the hell out of me, kissing my chin, neck, biting my lip, stroking my back.... I didn't reciprocate, but I didn't stop her either.

I've since spoken to DG, we've agreed that it's a shame we never had the right opportunity, and should remain friends, bury the secret and put the openness down to alcohol. 
I've also seen my girlfriend, and felt exactly the same toward her, if not with a touch of guilt. She actually told me something similar happened to her over christmas, and she basically told her friend no, I guess I should have told her then, but didn't want it to turn into tit for tat.

Can anyone make sense of this?!

Can you provide a brief overview of the text?
<bot>: Hot girl came on to me even though I have a girlfriend, didn't stop her but didn't reciprocate, did I cheat?
