So I've got a bit of a problem. My best friend's girlfriend has always had a bit of a crush on me, and has made mention of it several times in the past. Since she's utterly devoted to him and I didn't know her before they got together, it's never really been an issue beyond "whatever" to me.
In the last couple months she's been a lot more open to me and asking some advice about their relationship. Cool, I figured, I'm more than willing to help her, and by proxy my buddy, out if she needs it. This continues pretty steadily, and she becomes a bit more of my friend, though I still mostly just view her as his girlfriend. She comes by occasionally, usually with him, but sometimes just to hang out or whatever. I make dinner pretty often (I'm a cook), which she always claims is the best she eats.
A couple weeks ago she confided that she's been having wayward thoughts regarding her boyfriend. I told her it was kind of to be expected given that she's seen him at least half the days of the week for over two years now. Eventually she tells me that she's been having a lot of dreams about me, and came out and said that she's insanely attracted to me. I'm kind of taken back since I don't view myself in such a positive light whatsoever, but she insists on it and says she wants to see me the following day.
So the next day rolls around. She stops by my apartment and we decide to go get something to eat at a neighborhood pub that our circle of friends goes to a lot. We eat some food and have a couple drinks and decide to go back to my place and watch a movie. Sometime during all of this, she decides to come get under my blanket with me and cuddle me. Eventually this turns into petting, and is capped by a few deep kisses.
I'm honestly at a loss of what to do next. We've talked a lot the last few days and it's essentially been come down to that she's still hopelessly devoted to him but holds a flame for me and wants to see me again, and I'm having to use all my willpower not to fall in love with her. I don't want to let go of her, but at the same time I know that night was incredibly foolish considering her relationship to someone that close to me. I suppose I don't really want advice on what to do, considering I already know what I need to do but just don't want to do it. Has anyone here been in a similar situation and/or have any nuggets of wisdom to share about something like this?
