When it comes to affairs, most of them tend to fall apart, and there can be several underlying factors and reasons behind that.
While we can think of cases where affairs have eventually turned into healthy marriages—Duke of Windsor who abdicated the British throne and Frank Lloyd Wright, the famous American architect, each who seemed to have finally found their soulmates—most of us mere mortals don’t fare so well. Look up the length of affairs on Google and apart from one-or-two-night stands, the consensus is that most run their course in six months to two years.
Here are some of the psychological underpinnings to affairs that sabotage their ability to become more than short or long exercises in acting out:
1. The ‘affairing’ couple is united around shared misery and excitement.
Just as Romeo and Juliet were in part pushed together by being united against their feuding families, what often brings the affairing couple together is their shared unhappiness in their partners: This new person understands how I feel (as compared to my partner who doesn’t).
And like Romeo and Juliet, the beginning of the relationship brings excitement—of getting to know and feeling appreciated by a new person, of sharing your story to an interested listener, the excitement of breaking out—of the boxed-in life—of breaking rules, the excitement of new flesh and sex.
But eventually, all this fades—the talk of misery gets old or dies down, the breaking out turns into being broken out, the backstory is told, the flesh is no longer new. The relationship settles, and when it does, other aspects of each other’s personality, unnoticed before, rise to the surface. What each finds is another variation of what they don’t like in their partners.
2. Those involved in the affair really don’t know each other.
But not only do their shared misery and the excitement blind them to seeing each other more completely, so do their needs and frustrations with their partners. The new person is less a real person and more an ‘un-person’—the seeming opposite of the partner.
Where he was dramatic, this new person is steady; where she was steady, this person is spontaneous and fun-loving; where he was critical, this person is so approving and gracious. Yes, the new person maybe like this, but these qualities are only and unnaturally amplified by their contrast to the partner. The complex self is reduced to a simpler, one-dimensional one.
3. Everyone is on their best behavior.
Dating is different from living with someone. The rubbing of lives, the grind of daily routines creates stress, boredom, a host of normal reactions that couples who see each other for limited amounts of time don’t experience because behaviors are held in check—I don’t want to spoil this time by talking about ______.
The results are that not only are they not really getting to know each other, normal problems and resentments are swept under the run, are not resolved, and so only build up over time, usually leading to seemingly out-of-the-blue explosive situations.
4. Oxytocin eventually drops.
Oxytocin, the “love” hormone that bonds people together, that ramps up the sex, that creates that falling-in-love feeling naturally begins to wane after about nine to 18 months.
This is built into evolution, the need for both parties to stop staring into each other’s eyes and get back to work. When this happens, sex drops off, the passion and glow begin to fade. This is especially derailing for affairs initially built on physical chemistry.
5. Messiness and misery eventually take over.
While some couples and cultures tolerate extra-marital affairs, turning an affair into a more permanent relationship eventually turns into a mess for most on a lot of levels.
There are children involved or money; there can be contentious legal action which is geared towards emphasizing the worst in all parties. And with this comes stress and guilt and depression.
