Do not text asking "what the deal is?" What ever you do. For 2 reason I'll tell you why. Reason number one and most importantly; You already know what the deal is(in a sec you will). That's the biggest thing. Remember you know exactly what's going on, and you're not confused by what happened, what you're going to do about it, and will not be surprised by, nor unprepared for anything that could happen in the future.
So what IS the deal..."Was that kiss real or was it just the alcohol acting"... what the heck are you trying to ask her?... Was that kiss real?!? You could have just asked me that. Yes, you really did kiss her, it happened in real life, it wasn't a dream. But that's not what you really want to know, I have no idea what your asking, she has no idea, you have no idea, sounds awkward and uncomfortable. She gave you the best answer she could. "I'm not sure(what you're really asking me) but I wanted to kiss you." DON'T make it more awkward and uncomfortable, just drop it because of reason number 2.
She WANTED to kiss you. If you feel like you "Need help quick!" you're anxious.. Relax and play-on playa. The more you ask her to get rid of your anxiety the more uncomfortable she will feel around you.
What you should have texted her the next day was something like "hope last night wont be just a yearly thing
" You would have got a similar answer "i dont know hehe" but this time you're having fun.
