I didn't hear his show on Friday, so I can't answer to that. I do know that I'm not going to debate a question with you that neither one of us really knows the answer to.
Only Rush and Marta know that truth of what is going on. I suggest we leave it to them.
That was part of my original point when you posited one potential that Rush was divorcing Marta because he changed after getting clean. Its just as possible the reverse is true and that Marta is leaving because he isn't clean. Either way we don't know but both could be true.
