Mel Gibson Wants His Wife Back

Now that his love affair with Oksana Grigorieva has come to an end, Mel Gibson is missing his ex-wife, Robyn Gibson.
According to sources,

He’s still in love with Robyn, he realises he made a huge mistake leaving her.  Robyn is not only the mother of his seven children, she’s been a major source of strength for Mel throughout his life.  Without her around we’re worried he’ll fall to pieces.

Mel was married to Robyn for almost 30 years, but ended the marriage to be with his mistress, Oksana, late last year.
Mel also has a child with Oksana.
What do you think should Robyn take him back?
