Hi. You always have a chance as long have both of you at least try. The one thing that should be done is to make sure he is on your side about that whole familly problem. Ask him to organize a familly meeting (that can be complicated to do but in a moment like a divorce, you make the effort whatever is required). Then you two face the familly and ask them in plain face what is the problem they have with you and at that point if he is on your side and defend you, are in good hand. It does not matter that the problem get solved with the familly, what you want is to know that you can count on him from that moment with the familly problem. If he can't stand for you there, he will not be able to stand for much else in the future. It might be a good thing for him at the same time as he could "confront one demon's", literally.
