I don't know if Orson has lied or not but she can hardly accuse him of being all about the fame - which he may well be - when she says she lost all respect for him on the honeymoon, has talked to him and about him as though he's a piece of shit, and yet she's stayed which must mean she's enjoying the drama and the chance for a bit of fame herself.
She's really a very unpleasant person and while Orson might be a liar he doesn't come across as a nasty wee shite.
