Are you in a country Georgia or in the US state Georgia?

I’d think after decades in the country you have some type of legal status that won’t end because you got divorced? Of course I don’t pretend to know your situation.

Well why not separate unofficially? Just live your lives completely separately. You can even still live in the same house but lead separate lives. It’s not comfortable but it sounds like you have no other options

Most people don’t forgive infidelity. They say they do, but in reality they just decide to stay, often for just financial reasons. Deciding to stay with a cheating spouse isn’t the same as forgiving. So it’s likely not reparable at this point especially with a physical aspect.

I congratulate you on your sobriety. I wonder if years of not being sober contributed to your marital unhappiness
