Down for the count

So I just found out that another one bites the dust. He had a gf, yet he made it clear that he wanted me (in addition to her); however, I acted appropriately because I am not a homewrecker. But it was blown to a whole different level when I discovered that she LIVED with him. . .SMDH
(Side note: what makes a guy think that I will ever date him if he comes after me while he is in a relationship???)

It seems that people tend to blame me for the bad experiences I have had while in Winston Salem. I refuse to take the blame for the ruthless behavior of these guys; however, at what point do I take responsibility? Maybe I have made myself too easy and accessible. (I don't necessarily challenge the motives of their approach because, apparently, it is a huge step for him to approach me.)  Maybe I get too comfortable after the initial contact turns into decent conversation. (What can I say? I'm a homebody at heart!) Maybe I just think too simply sometimes. (When the words leave my lips, it's simple conversation. By the time those same words reach his ears, it's a cry for a lover???)

I think I should just go back to my roots: being super unattainable. Absorb myself in school and lab. Turn down every guy. If he is too cute to pass up, then he can talk to me/text me every now and then, but turn down all invitations for a date. If he is persistent and refuses to take no for an answer, well. . .I'll cross that bridge if/when I come to it.
(Side note: isn't it funny that as soon as I declare this out loud, all the men in Winston Salem want to pop out the woodwork and speak to me? Time to practice all the polite ways to say no!)
