Please pay more attention to posting guidelines. There is a Read First sticky in the Children forum (where this was moved from) that directs questions of a legal nature to this forum.
First you need to understand there are two types of custody; legal and physical. You have joint legal custody and I doubt if that will change. But physical custody is a different matter. Its very difficult to have joint physical custody, unless the parents live so close to the children's school that where they stay wouldn't matter. In that case, you should be able to have a schedule of alternate weeks.
If he left, took the children and did not inform you where he was, then he was guilty of parental kidnapping. If you can provide proof of this, it will have impact on the court's decision on who to give primary custody to. On the flip side, your willingness to allow him to take charge of the children in the family home while you move out may balance that.
This is a tough one to call since you both have issues. And you really need an attorney to sort them out. One more point, if he gets an attorney, then you will absolutely need one to protect your interests.
My gut reaction is, unless you live close enough to alternate weeks, he will get primary physical custody, since you let him have it. You should, on the other hand be able to get generous visitation.
