If your lawyer is representing you, I wouldn't have my h go along w/me. It is showing your h the way that you and your lawyer are going to handle your divorce against him. You don't want to show your hand to your h because when he seeks legal counsel he will share that info w/his own lawyer and there could be a long drawn out battle over the splitting of the assets and spousal support.
My advice, don't take him w/you as it is not in your best interest. Your h needs to seek his own legal counsel in this matter.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
