Always has but it came with the "perks" of coming back home to a foid who takes care of herself (not eating anything she sees on the fridge as well), takes care of the children that is truly your blood, protects your dignity whenever needed, do whatever you ask of her, cooks, cleans and do all of the boring stuff while at night being yours and yours alone. Of course there was never a 100% certainty she wasn't cheating on you but on those times there weren't many options for them. Now it's 100% that they would cheat on you.
In any case: water.
