From age 18 to about 22, I slept with every girl I could find, but one stood out as my girlfriend towards the end there. I began seeing fewer and fewer girls on the side; she suspected as much, but we both ignored the subject.
Then I met my wife. Cute, hot, funny, boobs almost as big as my GF’s! I started dating her, not telling either one the other existed. In time, they both came to know the other existed, but both thought the other was A) in the past, and B) not that important.
Truth is I loved them both dearly, and was in way too deep to break it off with either without hurting them a great deal. And I was a coward who enjoyed awesome daily sex.
Eventually my wife answered my phone at my apartment while waiting on me to arrive one day, and the last 3 years of deceit came to light as she and other GF compared notes.
Took me all day to talk my way out of that one.
Then, GF1 gave me an ultimatum. Get married or she’s gone. I chose gone, and she left, leaving me with GF2 by default. And in a couple of years, when she said it’s time to get married, we did.
Come September, it will be 24 years.
I’ve told this to my kids as a cautionary tale.
I was very selfish, deceitful, and hurt 2 girls I loved a great deal. It’s easy to see that and say that from the distance of time and maturity, but not so easy when you’re in the middle of it.
I’ve told my kids in no uncertain terms never to do this kind of thing to anyone, because no good can ever come of it. You pick someone, it works or it doesn’t, and you keep on going.
I think juggling is OK, but only if everyone knows what’s going on, so they can make their own decisions.
YMMV.
