I know where you are coming from and I'm not sure if it's the guys or the fact they may not be getting your emails. I have had a few winks/emails when I reply I don't get an answer even though they say they can't wait to hear from me. I wonder too is it me???????
Otherwise keep on looking and trying.
try writing again. what have you got to lose? but don't hang all your hopes on this one guy. there are so many fine fish in this sea, and if he isn't answering, you might be setting yourself up for a heart ache in the end by holding onto what you are imagining he would be like.
