Dude, married people live a life of quiet desperation. Sure the first year or two may be OK but after about 3 or 4 they sit across the table from each other, wishing they could run as far as possible in the opposite direction while they make small talk about trivial bullshit. They post pictures of themselves smiling and looking like everything is perfect on facebook, but that's just because no one stops for photos when they are screaming at each other; no one shows their underlying resentment and true loneliness in a photo.

The guy is so sick of his wife's constant bitching and moaning that he doesn't find her the least bit attractive anymore, then when he can't get it up because of this it is HIS problem. The wife fantasizes about some old boyfriend that she broke up with back when she was younger and life in general was more fun, a fantasy that is impossible to compete with. Whenever he gets a little time to himself he looks up porn and does his thing because it is literally more satisfying than seeing that same woman that nags, complains about her period, and goes to the bathroom in front of him naked. She keeps up communications with some guy she used to know that "understands" her so much more than her husband. What these two have is the most horrible loneliness imaginable, at least someone who is literally alone can be themselves, they can do what they please. Both these people are completely alone without those luxuries, they have to be "adults" and bottle their feelings of depression and loneliness deep inside until they forget who they are without each other, they lose their identities and resent each other even more.

I mean, or else they'll be truly happy for the rest of their lives, who knows?
