The Alpha's Regret

After two years of marriage, Jason suddenly filed for divorce.
He said, "She's back. Let's get a divorce. You can ask for whatever you want."
Two years of marriage can not replace his ex-girlfriend.
Sarah didn't make a fuss. She agreed and put forward her own conditions.
"I want your most expensive supercar."
"OK."
"Villa in the suburbs."
"Fine."
"Split billions of money you made in two years of marriage."
“???”
