it started out curious

Tonight I took care of a girl I met via social media dating. We had great conversation (except when I couldn’t hear her over the music) and seemed to click pretty well. I think I like her but I’m not making any quick assumptions. I’m not rushing / forcing myself into anything. That said, she felt comfortable enough to come back to my house for a couple drinks and more conversation. I honestly felt comfortable, which doesn’t come easy for me. I could tell, however, that she was drinking too much, too fast. We went outside and after only a short time, she was sitting on my lap hugging me and eventually making out with me. When I tried to stand up, I could tell IMMEDIATELY she was drunk beyond belief and the right thing was to stop...so I did. When I showed her the spare room to crash, she laid down and we made out some more, against some of my better judgement. She said she wanted more, but I didn’t think it was appropriate given we just met and she was very drunk (and I wasn’t, but that is beside the point). She ended up puking and I helped her along: held her hair, gave her water and reassured her as honestly as I could. So why do I feel like making the right decisions and helping another person, let alone interest, put me in a light of “the nice guy who helps”? I feel like by doing the right thing I’m either no longer an interest or I’m just boring enough to not want anything to do with....
