My ex went to see a divorce attorney once. The lawyer (god bless him!) laid the finances out for him and told him if he thought he could save his marriage, he should!
WE actually reconciled that time and had several good years together before his final MLC hit.
It's possible that your H went to an attorney and had the same kind of wakeup call, making him see what a dumb move divorce would actually be.
(BTW, it's still a good idea for you to consult with an attorney, just to learn your rights and how to protect yourself financially if H does file.)
