i think most of us here have pondered those or similar questions. as for our spouses, who knows? cant answer that one.
if you dont like your lawyer, then absolutely change. They should be willing to consider anything you say, and give their professional opinion about it. you should be in control, and they should be giving you advice and protecting you legally. If you dont want them to do something, they shouldnt do it anyway. But listen to their advice. also educate yourself independently.
you're going to go into a very tough situation, where you and your h will need to agree on many items. you'll need to discuss many things and make compromises. there will be plenty of anger and disagreements occurring naturally. Creating unnecessary conflict for the sake of revenge or to make yourself feel better will not help you and may ultimately backfire.
from my experience, the best way to approach this is very business like. be neutral if you cant act friendly. and by friendly i dont mean in a fake way. no need to pretend you dont know what he's doing, but dont rub it in his face. if he denies it, dont agree with him, but dont put up a fight. pretend as if it/he doesnt matter (which is different than pretending it never happened)
if you choose to divorce, then get the separation started and protect your assets. split your credit cards and your bank accounts (with your lawyers guidance) until the separation is begun, you are liable for his spending.
