Time to give up?

I'm not actually considering giving up on him altogether..but, I've been searching the web on how to save a bad marriage and ended up here..so, I joined.
I read the post on how often does he sleep on the couch? omg..every night almost. Usually falls asleep watching TV....and wonders why I care so much...How often do we have sex? never!!! Unless I initiate and do everything, his idea of forplay is grabbing a boob and saying wanna ****? Not that that's so bad...hey, it's better than nothing, right? That, his obsession with porn, and with our stripper neighbor (who happens to be a good friend...it's just that his fantasies are a little overwhelming to keep up with, it's not her fault he's hopeless). And the porn...I don't mind it, really..I actually bought most of our videos...but to stay up late just to jerk off and then fall asleep on the couch??? Come on..tact please!
Ok, I admit, I'm probably not in the best mood to be optimistic about any of his characteristics right now..but, I appreciate this opportunity to vent..even if it falls on deaf ears.
He's been promising me kids for 7 years...
His idea of a good time is going to any party where anyone will end up naked and on top of him by the end of the night (not that I mind that all that much...it's a 2 way road if he wants to play dirty...I've become very good at detaching from my emotions).

On the bright side, he's funny...extremely intelligent both book, and street wise, he loves animals..people are drawn to him (if we did divorce, my parents are sure to blame me and I'd be haunted with sneers from family members forever for my mistake)...the party is never dull in his presence...and I'm still hopelessly in love with the big jerk. grrrrrrrrrrrrrrrrrrrrrr
I've gone from a strong, independent, optimistic person....to this...a pessimistic whiner.
It's not fair to blame everything on him...but, I'm running out of steam.
What do you all do to get thru something like this?
