She plays the role of loving wife holding hands showing up and smiling adoringly at the dipstick in public.
In return for which he has agreed to pay her for prostituting herself.
We know she is in it for the money. She knows the dipstick had a lot of sex with other women who he paid off to shut up WHILE SHE WAS PREGNANT WITH HIS SON.
Any normal decent respectable woman would have dumped the bas**rd and moved on. She married him for his money obviously. She will do anything be anything pretend anything for a price. We have names for people like that.
