He's a total D-bag.

Dating someone but unsure if they're exclusive or not, and still looking for action on the side?

I don't accept this behavior from a potential partner, or even a friend! Seriously, I have mostly guy friends, and if I knew any of them were trying to play women like this, I'd totally lose respect for them (even if they weren't trying to game me).

You deserve better. Don't fall for this crap.
