jonsnow - look at it this way, if you were too much yourself and scared him off then he wasn't right for you and it would have continued on for a few more dates until you felt comfortable enough to let him see the real you, and he would have been scared off then, possibly after sleeping with him.
It's best to work out if you like each other for who you both are, rather than put on some front which will eventually be seen through.
Divorce - yeah its soul destroying isn't it?
If they're normal but disappear it's because they're talking to someone else more. They're not time wasters, they're just choosing to spend their time on someone else, because you're competing with hundreds of other women for their attention. That's the problem with OD.
I've lost count of the number of conversations I've let wither because I'm talking to multiple people and only one of them is interesting. Be that interesting person. Ask them about themselves, be funny, be slightly flirty but not too much. And they'll ask you out. If they're a dick, if they're not interesting and don't ask you about yourself in return, or just want to talk dirty, drop them early and move on.
Everyone is competing with other people for the time and attention of the decent ones. its a numbers game in more ways than one
