It is very frustrating to see very many spouses preferring GCs to their spousal lives! In this very forum, I have seen many cases where one of the spouses sent divorce papers as soon as they got their GCs approved! Especially for those who got EB approvals, the GC approval is unconditional. So, they don't need to worry about divorce after they get theirs approved. From what you are saying, I am afraid I am seeing such a possibility in your case. If your spouse would rather prefer to stay here single with the kids, what does that mean?
As I said in my previous post, if the arrest happened because of one spouse calling the cops, it would be better for both of them to pack and go to any other country where they can start afresh. Everytime they are asked about the arrest here in the US, that would hurt the victim spouse as well as the complainant spouse of that sordid episode that has created havoc in their lives. So, if the spouses wanted to firm up on their married life, they need to do what is good for BOTH. Again, if both of them are courageous and are happy-go-lucky types, they can set those things aside and continue to live together here, not paying much attention to the fact that one of them got arrested. But, BOTH must be able to prefer if they want to stay here or pack and go. Even if ONE of them says, "I only love to live here," then this to me is one of the clearest sign of an impending divorce. Again, it is my personal opinion and I have seen quite a number of folks shocked to be presented with divorce papers as soon as the plastic-card arrives by mail.
