What is the deal with men – seriously?

Example 1: This one I have an interest in is so fucking ambiguous, I don’t know where I stand from one second to the next. One minute, he’s flirty (is flirty the right word when referring to a guy?) and there seems to be no question that he’s interested, then the next he’s all distant and withdrawn.

Example 2: A guy I went to school with hit me up on Facebook chat tonight. I hardly spoke to him while we were in school – in fact, he even admitted that he doesn’t really remember me. Yet, by the end of our 10 minute (yes, literally 10 minutes) conversation, he was telling me that “he likes me” because I “seem like I’m on his wavelength”. The sad thing is, that 10 minute conversation was probably only 5 minutes because I was playing Heavy Rain on my PS3 during the whole thing and so wasn’t responding immediately! He even ended the conversation with “I’ll be thinking of uou.”

It left me feeling like maybe I’d agreed to marry him but had somehow missed that part of the conversation. :/

Can I have just a little bit of middle ground here? Ugh.
