If you were a cad, you wouldn't care.

Quit looking at girls as potential lifemates. You seem to have no problem hooking up with them. Just go with that. A right one will pop up. Make sure you're ok yourself - not expecting her to complete you, or your vision of yourself (this doesn't discount the "whooho!, we're like one!" feeling that can happen. Just wait, & don't rely on it).
Basically, quit looking for love. Women are put off by that attitude It'll come to you.
