From TMZ

Sources connected with the couple tell us ... Paula is unimpressed with Robin telling both TMZ and thousands of concertgoers he's trying to win her back. 

Here's the good news for Robin.  Although she TOLD him she wanted a divorce, she hasn't hired a divorce lawyer yet and she's open to reconciliation.

BUT ... before she takes him back, Robin has to prove his loyalty to her ... by his actions.  She's keeping tabs on him at his concerts, watching who he hangs with, which parties he attends -- especially the after parties -- and what photos surface.

We're told Paula knows photogs have their cameras trained on Robin, and she views the paparazzi are her private detectives. 

Robin has also been sending her flowers, which was seen being delivered to her Hollywood Hills house on Thursday, and it was clear that no expense was spared on the gesture.

They've been together for 20 years so I am definitely rooting for them.
