I'm just curious Sky, and please tell me to butt out if I'm overstepping any boundaries or just plain making you uncomfortable, but have you ever told your guy friends, "Hey, I like you. I enjoy our friendship. By the way, I will never date you."
As in, said those exact words?
Perhaps that's way too harsh to say exactly that. Is this something an asshole would do? Is it going way too far? Yeah, I guess. Maybe. I don't really know who you are or what your relationships are like, so really I'm not really addressing you, I'm just addressing a projection in my mind. Or the plural "you" in general, to anyone who is reading my ramblings.
But I get the feeling (from reading a few hundred words of text on an internet forum, so I know I'm onto something) that you have never explicitly stated with no uncertainty or room for doubt who you will and will not date among your close friends. There might have been assumptions about the boundaries of your friendship. If your expectation is that absolutely zero of your guy friends will ever ask you out, you have nothing to lose by telling each of them, to their face, that you are not available for dating. If you expect that some of them will ask you out, and you don't want them to, why shouldn't you communicate it explicitly? Why leave it open to interpretation? Why leave yourself open to unwelcome solicitation if you are certain you will take no one up on their offers?
Do you think your friendships would suffer by setting such strict boundaries? Do you think you'd lose something? Would you suffer from lowered esteem among your peers for asserting yourself? And if you lost a guy friend because you were so clear, so unambiguous, and so direct about it, would it have been alright to instead just let the friendship to continue without correcting his thoughts and feelings toward you?
I don't know what's going on in your life, so I won't pretend to know I'm speaking directly to you. But you are someone who can answer those questions.
A lot of guys deal with rejection in different ways. Some guys, after being rejected or breaking up, will take stock of all the available women in their life. Or rather, "available" women, which is to say desirable women they know. And if their female friends are on that list, some guys will roll the dice.
If I'm coming across as rude, or presumptuous, feel free to say so, in as many words. I'm not here to sap away your time or harass you if I find your answers disagreeable. I'm genuinely curious, and I promise to not to drag you into a multi-post conversation if you're just not feeling like obliging me.
