The 'Baggage Claim' actress split from the 'Blurred Lines' singer last month, and though she was reportedly having second thoughts about filing for divorce, insiders say she has yet to decide whether to give her spouse of eight years - with who she has three-year-old son Julian - another chance.
According to gossip website TMZ, Paula is ''spending a lot of time thinking'' about her marriage, but is yet to feel convinced by Robin's efforts to prove he can be a good husband.
It was recently claimed the 38-year-old actress had told Robin, 36, to stop trying to win her back with gifts.
A source said: ''She's insulted that he thinks he can win her back with pricey gifts. He knows what it's going to take, and it's nothing he can buy with money.''
And the 'Mission: Impossible - Ghost Protocol' star is said to be unhappy with Robin's public declarations of love for her.
He told his audience at a recent gig in New York's Madison Square Garden: ''When there's someone you love, you gotta fight for them no matter what.''
And days earlier, he said during a concert in Atlantic City: ''Never stop believing and you never stop loving. And even if it is over, make sure you treat each other right. Treat your family right. Take care of your mom, take care of your kids and good things will come to you. Just keep believing that God is good.
''That's what gets me by. Sometimes when I get a little scared or worried about the future, I just try to stay positive and do my part to spread love and spread joy.''
Though the couple insisted their split was mutual when they announced their separation, it has subsequently been reported that Paula told her spouse she wanted a divorce and Robin did everything he could to get her to change her mind.
