I know someone through a hobby who left his wife of 25 plus years to be with a woman he'd known for quite a long time and had been having an affair with. Five or so months later he's desperate to get back with his wife. He used the phrase 'I want things to get back to normal'.
I really wonder in these situations what's happened, i.e. has the new woman turned out to have a different character to before, or does she have annoying habits that weren't apparent when they weren't living together, or is he comparing the new woman to his wife in terms of their behaviour or what they each do for him, etc. Basically, what was he expecting after being with the same woman all that time! - is what I want to ask him.
