What about Miriam?

OK we're all good and sick of Bertie and his escapades - but what about Miriam Ahern?
Why is she staying so quiet?
If my ex-husband was using our break-up and ME as an excuse for his tally-ho, I think I'd have something to say about it. (I don't have an ex-husband, thank God, they sound like nothing but trouble!)
If my ex-husband closed his bank accounts, dealt in cash, seemingly hid money and did me out of my due marriage settlement... I doubt I'd be silent! I doubt I'd be invisible! I doubt I'd hang out with him in public like Miriam did during the election!
How did Bertie swing the election is an easy one compared to - how did Bertie secure Miriam's support even though he "done" her?
The most cunning of them all, boy!
Did he promise her the moon?
Maybe we're all wrong about him and he's a great guy?
Miriam! What's the story?
