In dating, should I protect my ego or risk rejection to stay open?

I mean obviously in dating getting played and such is probably inevitable. Now the question is if you play the game willing to get your ego bruised or you just can't handle the embarassment and withdraw alltogether

I mean if one refuses to open up ever they might throw out the baby with the water...

Repelling everybody you will also miss out on the good few
