depend the circumtances, if you have small childrens and can't afford live alone taking care of them, better stick with him till the appropriate time is coming.

If you have no children and you are fine living without him, diched him in the minutes you found out he is going the other way. why bother living a lie. you deserved to be loved completely.

If you think he get treatment and back to normal then you should support him.

Everybody is right Everybody is wrong, it depend where we stand.
