Hi Alphacourse, I have lived your question for 4 years (discovered the cheating in 2009, also 2 years, he is ashamed, in therapy), so I think I am qualified to answer it.
Red flag no1: he has no friends
reg flag no2: he is ashamed.
red flag no3: he did it for an ego boost (his own admission)
Shame is NOT remorse and it is NOT repentence. (Very old fashioned words, very important dynamics). Shame is the other side of the toxic void that he tries to cover up with the buzz of having his ego tickled.
After 4 years of 'reconciliation' (where he carried on being exactly the same as he was before), and being warned by my IC that he was a narcissist and would not change, and finding out OW yet again, I am filing. But it hasn't been a wasted time (except the trying to connect with him and the hope), I have changed a lot myself.
They don't change Alpha. If they do change they do it despite being left (and work to come back to you).
I know you are not going to hear me right now, but I advise you to stop investing in this person and certainly stop hoping that he gets it. Oh, he gets it, all right. Entitlement and using people.
Chumplady: Veronica Sawyer: Heather, why can?t you just be a friend? Why do you have to be such a mega-bitch?
Heather Duke: Because I can be.
From the movie ?Heathers? (1988)
Why do cheaters cheat? Because they CAN. It?s that simple. Do you need more of an answer? Okay. Because of greediness. Because of narcissism. Because of a lack of empathy for others affected by their shit decisions. Because they value ego kibbles more than they value your well-being. But the reasons simply boil down to ? greed, opportunity, and not caring.
One very common mistake the Cheated Upon make is believing it is all way more complicated than that. They will invest all their energy in a pointless exercise trying to figure out the cheater ? their FOO issues, their astrological sign, their addiction issues, their birth order, their purportedly low self esteem. (Newsflash ? they don?t have low self esteem. They actually DO think they are better than you and more important than you.)
Figuring out the cheater is energy directed at THEM, which is energy deflected away from YOURSELF. You?re asking why they are this way, instead of asking yourself the harder question of ? why am I hanging around this megabitch who?s not my friend?
I call this stage ?Untangling the Skein of Fuckupedness.?
The skein is impossible, but by GOD, you?re going to unknot it, piece by piece, make it linear and you WILL understand it.
Untangling the skein of fuckupedness is a coping mechanism. You want to figure out what makes your cheater tick so you can ensure that they never do anything so devastatingly hurtful again. If it?s their FOO issues with their mom, well, you?ll call and make that counseling appointment for them. Untangling the skein is codependent behavior. Not only will you make the counseling appointments, next you?ll get your magic marker and highlight all the relevant chapters in the affair books you bought for them on Amazon.
Stop it! Stop it right now! It?s not your job to figure them out! You only get to figure out YOU. What your values are, what you will tolerate, and what is acceptable and unacceptable to YOU. That?s it.
Most cheaters are very invested in you getting lost in the skein of their fuckupedness. Hell, they don?t have to invent an excuse for their behavior, you?re doing all the work for them. There is nothing they can say by way of explanation that is not self serving and self pitying. The only thing a cheater can do is DEMONSTRATE they have remorse through their ACTIONS. Preferably a very generous divorce settlement. Failing that, a very generous postnup.
An explanation is not a balm. Getting lost in the skein prolongs your pain. Better to move towards acceptance. They did it because they COULD. So? now what? That?s on you.
