He's CHEATING on you, and you asked him for a HUG???
Blccccch.
Agree with luvless -- you need to suck it up and come up with a plan here. "Neediness" isn't attractive, and I know it's sad, but your husband, while he's cheating, CAN'T be the source of your comfort right now. That's going to have to come from within yourself, and from your friends and family, and from us on here for awhile.
What is your financial situation? Have you consulted with a family law attorney at all yet? (doesn't mean you have to DO anything yet, but you should know what your rights and responsibilities are, and it will help ease your mind).
