PB, women are more sexual then men are, the ability to have multiple orgasms quickly should give you a clue about that. If you're not "doin' it" for her and she gets bored with you and asks "are you done yet?", huge problems there.
Don't concern yourself with WAW or MLC, concern yourself with showing her the way out since she had an affair. Chasing and pursuing her even though she disrespected you is only going to win you more disrespect from her.
Rob,
Man, that's more wisdom-per-word than I think you've ever accomplished. You're HIGHLY EFFICIENT today!!! lol
