This might be a TL;DR kind of post so bear with me. I know I'm going to get the usual flamers that will ask "Why are you asking a bunch of nerds on the internet about this stuff?" but I'm ready for them. I've seen some pretty sensible people on this site when it comes to this kind of thing so I don't think I'm barking too wrong of a tree.
So a little bit of background on this situation:
Last Friday night it was a friend's birthday and we were going to pregame at her place and then find a party we got hooked up at. However, a few drinks of Jameson whiskey turned into a whole huge ass bottle and we ended up getting knocked out. Saturday, I was feeling super shitty so I decided not to go out to party. However, the friend who just had the birthday (Lizzie) still had some party left in her and she wanted to make the most out of her weekend. I was not actually going to go, but then she was going to bring along out other friend, Maddy. I'm really good friends with Maddy since me and Lizzie met her back during orientation (sophomores in college now). I had chemistry with her last year and I see her in 3/6 classes this year. Since I met her I fell for her and I've really enjoyed being her friend. It's pretty clear that I will pretty much have no chance with her, but I'm okay with that. As for looks I'm going to go ahead and say I'm pretty below average (she's definitely 8-9/10) and I'm not exactly the most 'fun' guy either. I'm going to go ahead and say I'm friend material for any girl.
Maddy is a studious girl thats the innocent type, but that's just because of her parents being oppressive. When she parties.... she really parties. I've had to bring her home once and I was really afraid that she would die of how much she drank. I knew that Lizzie would not be able to watch Maddy to the best of her ability so I offered to go along as a sort of "babysitter." Maddy was really excited I was going along as was I. She was looking exceptionally amazing that night and I was really happy I was her sort of "escort" for the night.
We get to the party and she has a few too many cups of jungle juice in the beginning and she is getting wasted on the spot (she's a real lightweight). Our party gets busted and we all bail. Through Lizzie's hookups, we get to go to another party. Here is where the "real" party begins. Maddy gets even more drunk and she makes out with three different guys. Maddy isn't a slut when she's sober so I won't judge her for that. She gives one guy a hardcore lap dance and she was shaking everything her momma gave her. Because I really like her, I couldn't even bear to see her do that stuff. I wanted to stop her from doing all of that, but Lizzie told me that it wasn't my call. In the end, I didn't really live up to my self-appointed job of the babysitter and I felt really stupid. After all the times I told myself I would keep her from doing that to herself, I pretty much failed.
The whole night she would randomly come over to me and give me a kiss on the cheek and a hug and tell me how I'm her best friend ever (something she would never do sober). Since I'm pretty shy, it was awkward, but I will admit I liked it. On the ride back she kept on complimenting me how I was so sweet that I actually took care of her the whole night. She pretty much went to sleep in my arms the whole ride back and I'm not going to deny that I really loved her complimenting me. However, since she was drunk, I felt wrong for feeling like that. I felt like I was taking advantage of the situation. I didn't touch her inappropriately or anything, but it still felt wrong once I was alone. On the walk back to the dorm I pretty much carried her back while she had her arms around my neck and she continued to call me her best friend ever. I even held her hair back when she puked, ran to the store to buy her some water, and all our friends commented on how obvious I was being.
So anyways, here's the question. Did I fuck up? I promised myself I wouldn't let her get out of hand but I did. I'm the hopeless romantic type so there was no sexual feelings involved in the whole ordeal but I think I get really guilty, really fast. It was her call and her decision, but I still feel guilty for letting it get to that point. My female friends tell me that I'm the sweetest guy ever for watching out for her, but my guy friends say that I shouldn't feel guilty for anything since she's not my responsibility. Also, was it wrong of me to actually like taking care of her when she was drunk? It doesn't seem right for me to have liked her getting into that state. Sorry for the long post and how stupid I sound by acting like a five year old that did something bad.
