Sources say that Paula Patton is not impressed with Robin Thicke crying over her on stage -- and he would need to do much more to get her back. As previously reported, the couple released a statement last week saying that they've decide to split and Robin has admitted that he was fighting to save his marriage. But there may be hope for Robin after all -- sources told TMZ that although Paula asked him for a divorce, she hasn't hired a divorce lawyer yet and she is open to reconciliation. If she does take him back, Robin must prove his loyalty to her by his actions -- and she will be keeping tabs on him at his concerts, watching who he hangs out with, which parties he attends and what photos surface online, etc. Meanwhile, Paula took to Instagram to post a cryptic message, writing, "Everything happens for a reason. If you love something let it go, if it comes back to you it's yours. If it doesn't, it never was, and it's not meant to be."
