Her Husband Called-WHAT?

SO, HE, the one she says doesn’t get involved unless things get out of hand, called Keith at 9:09 am. He called Keith to ask when Keith was sending him the airfare he owes him, adding, “I’m not a rich man either.”

Huh? Now, Keith owes her husband? I thought this was all just between Keith and his ex, according to what his ex says. Keith didn’t call back.
