No worries, CVX was just one
long grind for me as well.
And my tolerance for crappy stuff is much longer than most people's. When you start RE 5, RE 6, or RE Revelations 2, and if you have a PS3 be sure to friend me and I'll be you coop partner.
I've done them on single-player and trust me it's better (and easier) when your partner isn't a bad AI. Operation Raccoon City might be the only exception to this rule, but that was a damn fine game.
