He put you, personally, YOU, into an uninformed, non-consensual, unanticipated, non-negotiated, group sex situation at the ripe old age of fucking 19 years old.
Like, I've and likely we've, as in many/most of us, have known of or at least heard about 29 year olds, 39 year olds, 49 year olds, 59 year olds, even 69 year olds (I was going to exclude 79 year olds, but adult homes and assisted living communities continue to have some of the highest new transmission rates of STDs) who have had spectacular melt downs and not coped particularly well with group sex, even if it was fully informed and fully consensual and not SURPRISE! GROUP SEX!!!
You had group sex sprung on you like the OG version of a BAD IDEA SURPRISE PARTY! at AGE 19.
Your 'special relationship' with your early on, possibly even FIRST 'Special Person' got devalued and 'un-specialed' in a heartbeat. And so did YOU.
You did what any (understandably) short sighted 19 year old would do: you dished it right back.
IMHO, OK, honestly not unreasonable, at age 19, unmarried, no kids. (That's going to be an unpopular opinion on SI for a number of reasons, all valid.)
Your problem is between you and yourself.
You allowed his boneheaded, selfish, manupulative move to push you into a place and into an action that you would not have chosen on your own, for yourself.
You had the unpleasant but instructive lesson of experiencing that first hand.
It was not who you were, it is not who you are.
This is the nuanced, unanticipated, poorly understood experience of 'the regrets of revenge.'
You were not, and apparently are not, a naturally promiscuous person.
(No offense to those who are naturally, of their own informed choice, responsibly, honestly, maturely promiscuos.)
Sex with an outside party, and especially for a third degree, adjunct reason (revenge) doesn't work for you.
It violated your personal space. It cheapened you. That wasn't, and it's not, OK with you.
You learned about that, and about yourself.
And *that part* is not a problem at all.
That, is A Good Thing.
And, you learned it at the ripe old age of 19.
THAT. IS. HUGE.
Congratulate yourself!
It takes many if not most people *DECADES* to figure that out.
Your partner/husband went on to have six (6) affairs.
Obvs, at that time at least, sexual monogamy was not his thing.
Gonna bet, sitting here from this perspective, that had *exactly zero* to do with you.
He would have done the same regardless, to anyone else, with anyone else in his life.
Is he still the same guy?
Does he still want the same stimuli, the same experiences, the same exposure?
Or, has he evolved?
Do you feel safe right now?
Can you forgive and most importantly live with the flotsam and jetsam from your early relationship?
IMHO, if not, that's OK too. (I continue to struggle with those exact issues myself, so I do understand.)
He's told you that your ONS did not cause his six affairs.
That seems remarkably honest to me.
Work with that, try to understand what that means in the context of a long term relationship, which obvs has many other inputs over time.
In SI parlance, revenge affairs/involvements and especially one night stands are known as 'Mad Hatters' or 'mad hattering,' i.e. Your significant other did it, so you 'evened the score,' you did it too, SO HOW DOES THAT FEEL??? In very superficial ways this is somewhat similar to your situation, but IMHO, 'mad hattering' typically involves much more 'sunk cost' at that very moment of the revenge infidelity: marriage, legal agreements, perhaps children, comingled finances, property.
NOT dating, discovery/self-discovery, burgeoning sexuality, and bungling along through the end stages of adolescence with tenuous commitments.
Shit happens. =(
(Hubs 'adolescent OOPSIE! happened five years into marraige with comingled finances, two babies in tow, and under contract/in escrow for our first house. IT WAS A GIANT HEAD FUCK WHEN IT HAPPENED. AND IT WAS DISTINCTLY DISHONEST AND *NOT CONSENSUAL.* BONUS ROUND I ONLY FOUND OUT ABOUT THE TRUE EXTENT OF IT A FEW YEARS AGO. CUE GIGANTONORMOUS HEAD FUCK.)
Fortunately (I guess it's 'fortunate,' LOOK AT ME, I'M HERE ON SI) Hubs seemed/seems to have felt as badly about that incident both then and going forward as I now do.
He knew the whole of it as soon as it happened, as soon as it was over, so he's felt like shit about it for many years.
I've only had that particular privilege of feeling like shit about it for the past few years.
Still, head fuck.
I see no indication that infidelity in particular was repeated, although General Immaturities and Low Emotional Intelligence (THANKS, FOO!) plagued us for decades.
Much better now, ironically, BECAUSE I BLEW THE FUCK UP AND BLEW UP OUR WORLD after discovering the true nature of that long ago infidelity.
NO. MORE. RUG. SWEEPING.
YMMV.
