Just because they have been together for many years doesn't mean they're fucking each other. You have already seen that Sammy fucks just not with Melinda. I'm pretty sure Melinda knows about it but stays because they want the relationship to work (or likes the money) but eventually says fuck it and moves out. Melinda might also be fucking others on the side as well but is more discreet and she probably has them use protection or she is fixed to prevent herself from getting pregnant.
