After the announcement that he and his wife had decided to separate Robin cancelled a few shows but now he's back to performing - before his show TMZ found him at the airport and asked him what was going on and he said all he was trying to do was get her back!! 

And then at his show he told everyone what was going on and how he's going to try and get her back because she's a good woman...and then dedicated his song "Lost without You" to her - which btw he wrote that song for her! I don't know what I would do if I was Paula - I don't know what Robin did, but man I'm a sucker for songs being dedicated to me! I hope these two can find a way to work it out - Marriage is tough but it's always worth trying to work it out!
