I think the answer is in the last scene (I think it was the last) when Rick is talking to Herschel. Rick says he has to get the group in fear of their lives so they will agree to give up one of their own (meaning give up Michonne to save their own lives).

Sometimes, Rick needs a kick in the rear to make his brain function.

In the end,I don’t believe he’ll end up handing her over, either, but he may do some dithering before it’s all over (and yes, a kick in the rear will be in order, I suspect). I think Rick is essentially a good man, though, despite his problems. And I’m thankful Herschel is there to act as conscience.
