Date them all.. especially the one you find most attractive. After all folks always want what they feel they can't have.
And the East Coast guy? I'd suggest it was time to meet in person or call it off. The longer you go without meeting an online individual, the more the mind fills the blanks with perfection. And the easier it is to be involved without ever meeting. Just smack him upside the head.. geez.
I peeked at one of the dating websites and just inwardly cringed. How do I get over that?!?
