Jon Gosselin misses Hailey Glassman

Even though Jon Gosselin and Hailey Glassman are officially taking a break, Jon took the opportunity to try a little bit of redemption.

He apologized to his ex-wife Kate, for dating someone in the public eye so quickly after their separation.  

Jon said, "I want to apologize to Kate in private.  I'll apologize to her for openly having relationships in the public eye. That was a huge mistake, because if she would've done that to me, I would have been extremely pissed off. Not because our relationship is over, it's almost like a stab in the back. And now that I think about it, it was a very wrong thing to do. I definitely regret it."

And today, he tweeted that he still misses Hailey:

Going home to see my kids,-excited, but i'll miss Hailey =-(. She has made me realize I need to be an honest person/father for my kids.

Think he's being sincere?  Or is he getting to be a good actor?
