Gloria is Felix's ex-wife, whom he spends almost the whole series pining over. Gloria divorced him on the grounds of pestiness, and even though it's clear that she still has feelings for him, she can't stand living with him. He was always insanely jealous, and unwittingly made her feel inadequate, by re-cooking her meals, and telling her how to set the table and do the laundry. Depending on which episode you're watching, Gloria's maiden name is either Fleener or Schaefer.
