There's this best friend of mine who has been showing clear signs that she wants me to go out with her. She is an amazing girl, and I am very honored that she has feelings for me. When I first realized that she liked me, a few sparks of interest rose, but as time went on, for some reason I just kept (and keep) getting this feeling that I shouldn't date her. I can't explain it. Every time I think of dating her, my whole body just shuts down in rebellion towards the thought (that's not to say she would be a bad girlfriend, its just that I would end up being a bad boyfriend for not returning my feelings for her in the relationship).
This past Saturday, we cuddled for a bit after eating at a restaurant with friends. It felt good at the time, but I realized that it was a baad idea to go along with it because that's basically leading her on. I don't want to continue to lead her on, so I'm trying to come up with a way of telling her that dating just isn't a good idea for me. We have a "date" for dinner this Thursday which complicates me telling her we shouldn't date even more. A friend of mine suggested to just go out with her and see how things go and work things out as they come along, because she's more likely to stay my friend if we break up compared to if I tell her I don't want to date her. I'm not too hot about that suggestion, though.
What should I do?
