It is not 100% pickup related but I think noone could help me more than you guys in this situation.
There is a girl who is one of my best friends for like a year now. However, this can't be compared to my friendships with other guys. I noticed that I have to game her on a very light level to keep things going and always exciting. I've never thought that I would date nor even bang her so our relationship never progressed that way, and I think she would tell the same.
But - as if it was a proper relationship - things have started to get worse, more boring, less contact, and I froze her out for like 3 months. Just not replying, she texted me one or two times but that was it. A week ago we bumped into each other drunk and started talking again, texting the whole week, than meeting up next weekend.
All started well, but it ended really badly for the two of us. We were going somewhere, just the two of us, when one of my mates (who was attracted to her) texted me that he also wants to come, I said alright, of course he can come. I thought the 3 of us could lead to some embarrassing moments so I decided to invite another mate of mine so we were four. And the girl and the friend who asked to come along started to make out. I don't know why, but I immediately felt really bad about this. I can't explain it really, I can totally honestly say that I'm not attracted sexually to this girl but still, somehow I love being with her and it hurt me a lot that they made out than went home together. I was really drunk and so was her, so I cant remember properly, but I got the impression from their behavior afterwards that I was looking upset about the whole thing (i was!). But since we are only friends, I don't know if my disappointment is justified.
Next day she texted me if I am mad at her and I replied no, but a little disappointed (which I am, a lot). She told me that she is disappointed with me, too, and asked what did she do to disappoint me. I haven't replied yet, but don't know how to handle this situation. Gossip has already started about my hidden feelings for this girl etc. etc. I would welcome any advice.
