Wow. Sounds like he wishes he was still married to you and is starting to see the OW for who and what she is: "Astroturf." Careful though he may want to have his cake and eat it too. But it certainly made me laugh with his sudden putting of Beast on a budget.
There will be no cake. The cake is a lie. LOL! Thing is, even if that is what he wishes for, I'm better off now than I was. And I'm so much better than Beast is - because I'd never get involved with a married man, even if the person he's married to was the one he cheated on me with, ya know?
Let him continue to mow the Astroturf - it'll still never feel or look as good as the real thing.
