high maintenence

i worked with this guy who was married to the most extremely high maintence girl ever. she ran him like i dont know what. they worked together and had no children so they were literally together 24/7. he was the nicest guy ever. he really loved her and put up with so much,but he hung in there like a trooper. everyday she had to have pepsi. not just any ole pepsi. it had to be pepsi in a bottle(no cans!)purchased from a specific convenience store(they kept it the coldest). he had to transport it in a cooler and go to a specific dunkin donuts to get two 32 oz cups filled with their special crushed ice and place them in the cooler as well. there were specific instructions on how to pour the pepsi into the cups, but i dont remember them all and wont bore you with those details. you get the gist, right? super high maintence. the pepsi stuff is just the tip of the ice berg, but he did it. is it me or is there a pattern that repeats over and over amongst the majority of couples? really nice guy with demanding hag or super sweet girl with emotionally unavailable man. he once told me he liked the challenge of trying to please her. what? wondering if i ever break my dating hiatus if i should change everything up and just be a demanding be-otch and see what happens.
