WhY mE?

What is it about me that fails to make friendships with guys just friendships lately? It seems as though nearly every guy (with the exception of the obvious) I've made friends with since I came to London has at one point or another misunderstood my friendliness. Friendliness does not equal flirtation....how clearly must i spell it out? And if i'm not myself (friendly), then it is understood as bitchiness. So, is it my fault that perhaps the line between flirtation and mere friendliness is more blurry to some then to others? No, goddamit!!

Every time I notice any kind of attempts coming from a "friend", I pretend as though it's nothing (i.e. i ignore it), yet the more i ignore it, the more blatant they become. Do they not know me enough to notice when i am not showing interest, or does the testosterone kick in and they just block out the fact that we're first and foremost friends? Or is it that perhaps we're first and foremost man and woman, and then everything else? I am beginning to feel as though it's my fault...as though i lead them on, but it's hard to understand when to stop. I'm used to being a part of "the guys" with my friends from childhood, so this whole making something "more" happen with guy friends has never been an issue i ever even thought about. Do i have to start now? When have we stopped being children and allowed the "real" world to swallow us? It feels as though I need to put on a veil of aloofness around some of "them"...it's a mine field out there.
