You could have responded but I don't think it would have changed anything. He seems pretty blatant about what he wants. the only thing I think is screwy is him demanding/telling you that you hae to move away. You don't have to go anywhere. If you want to stay in your town, why not? He isn't a dictator who gets to decide where you live and when and how. He is understandably upset and hurt but that doesn't mean he gets to tell you where you live and you have agree to everything he says. It doesn't work that way.
In the wise words of one (well, two) great friends here... ClingingToHope and ImprovedRomeo....... Don't be a martyr!
Yeah you were wrong but that doesn't mean you just agree to whatever he wants in the divorce and you leave so he can be happy that you are no longer in his immediate radius.
If you aren't in agreement, contest it. Did your L respond to the petition already? I would advise you do that and soon...
Your mom is on your side and is listening to you on the phone so that is good.
