I am conflicted...?

Okay...My husband and I moved to ok from Ca around a year and 3 months or so ago...he is very unstable as in he always wants to move. He never knows if he wants to be with us or not either. He wants now to move to reno nevada, but the last 3 weeks he has abandond us and was very verbally abusive to me and said he was never comming back. He then said he was comming back do to me saying I might consider moving out to ca again. Now all of a sudden he loves me again and is willing to work things out, but I don't believe he is serious. I think it is a game to get me and the kids back that way where he wants and to leave me again. He is very unpredictable. Should I go back with him knowing he will most likey leave anyways because we have kids, or should I stay here? Should I go to where he is just because of our kids? Ask me questions in email if need be...
