I made a new friend last year through work, she is lovely, has been a great help to me in lots of ways. She is very openly gay.
Since I've known her I've always had half an idea she found me attractive, but I valued her friendship and I always identified as straight so just kind of ignored it and pretended I didn't know.
Before Christmas she made a bit of a move, and I explained that I really wasn't into it, we moved on and things were fine. At the weekend we were both at a party, there was a lot of drink involved and when she made a move, I reciprocated.
I feel terrible, she is so pleased, I've tried to explain nicely that we were drunk, it doesn't freak me out but I don't want it to happen again. I don't think she quite believes me. She's a sensitive soul and has little confidence, despite being a great person. I've tried really hard to build her up and now I'm worried that rejection will knock her right back down.
I don't want to hurt her feelings, I want to keep her as a friend, but I have no idea how to say "I don't want this at all" without making her feel worse about herself than she already does.
