So you got this guy hooked for 13 years by being mostly a "good friend" to him and now you not only decide you want to have sex after all (just not with him) but you already even got to emotionally cheat on him by declaring your attraction to this other person.

And from your post, the only reason you didn't already have sex with this person who's not your boyfriend is because **she** refused.

And that's somehow not shitty of you.
