As an uninvolved outside observer? He's a selfish, self-involved guy masquerading as a caring guy. This is, I think, why some older men seek out younger women -- because inexperience makes it harder to spot the unaddressed personality flaws hiding under the mask. Harsh, yes, but not moreso than he deserves. He wants whatever he wants and he'll say whatever he needs to in order to get it. If you value your own mental health and happiness above all else, leave. If you feel the need to give this relationship another try, have him read everything posted here and then give him a chance to show you how he's amending his ways, starting with telling W about his infidelity.
Btw, your post from 10pm yesterday seems to have been cut off mid-sentence?
