The "easiest" way for one of you to move out w/o negative repercussions is to get a temporary order. That's what my ex and I did. It set out temporary custody and support arrangements, and with those my ex felt safe in moving out. You might want to explore that option.
Otherwise, learn to deal with each other. My ex and I did for 5 months while waiting for the temp order hearing. It wasn't easy, but it is possible. And that's even with a (significantly) less than amicable divorce.
