In the past year I've been with this girl a few times at the end of a big night of drinking. It's been a friends with benifits thing, nothing serious. But between the last time I was with her (maybe 6 months max?) she and my friend have been snapchatting/msging each other. So I know there was something goin on.

Anyway, last night had a few beers in celebration of a event we had and by the end of the night she was dragging me to bed. 

I didnt think much of it considering I'd done it before, but after waking up this morning I feel guilty/regretful. Not sure I should feel this way?

AITA?
