Yes bravo Ian. Cindy is nothing to him if anything he did give her roof and actually put up a great deal with regards to her nasty & manipulative behaviour.
If Cindy who has a massive chip on her shoulders from the beginning , who thinks the world owes her a favour, who thinks Ian owe it to her to give her roof, then thank goodness it all blew up in her face and Ian finally had enough & chucked her out.
As long as she's out of that house then she can stay under the bridge , in the gutter wherever because that's all she deserves.
