So my buddy had some people over to his house on Saturday. We were all kicking it, playing beerpong/quarters and just having a typically good time. There's this girl there who I recognize immediately that I met the previous week. Last week we hit it off with good conversation, very strong kino and eye contact, and being beer pong partners. Although I should have kiss/# closed the first week, I wasn't stressing because I knew that I would see her at my buddies house again (I think these are much less important in college game, especially if you know you will be running into that person in the future).

Anyways, as the night progressed she was getting more and more over me. I wasn't really doing anything, just having a good time, cracking jokes, and (terribly) attempting to freestyle. She kept linking her arm with mine, holding my hand and continued being generally touchy so I knew I was going to make a move tonight.

One of my friends who was hanging with us could plainly see what was going on, so being a good dude, he left us alone. I took the opportunity to isolate and told her "Come on, I need to show you something." She followed and I led her to the upstairs porch and continued to kiss close. We made out heavily for a good 10 minutes and then I broke off saying I needed to leave with my friends who were waiting (It was late). I said my goodbyes, told her we should do this again and left forgetting to get her number.

Now here's where my questions arise: The next night after she adds me on facebook, I message her saying that I had fun last night and tell her to give me her number. She does that and then today I get a message saying that she should probably mention that she also hooked up with my friend who owned the house after I left with a frowny face at the end of the message.

In what way/frame should I respond to this message and situation in general? While before all of this, I probably would have been mad at her or my buddy but coming from an abundance mindset I was surprised to find that I really didn't care too much. She's pretty cute and I would hook up with her again, but I'm not going to really put in much effort.

What do you guys think? Advice?
