Are anti-feminist women more likely to expect/tolerate cheating from their partners than feminist women?
Almost certainly more likely to tolerate cheating. The old traditional model exchanges his money as breadwinner for her work raising children. It is widely accepted that this is not so much about love as security. It has always been acceptable within old traditional style marriages to have discreet affairs, the man would take a mistress, and perhaps provide for that mistress, but the unwritten rule was always that his first loyalty should be to his wife. The wife would turn a blind eye to his behavior (provided he didn’t rub it in her face) knowing that they were in it for the long haul, and that she was a dependent. Historically, such women are far more likely to leave their husband if he can no longer provide for them, if he loses his job. Discreet affairs, while not welcomed, were and still are widely tolerated.
