I have had this done to me – in the distant past. But i can tell you it has affected my trust of men in a disgusting way. What you did was selfish and sneaky and self serving. I have no empathy for you at all. You didnt care until you got caught. You didnt mind doing that to his wife – while she lay beside him.
Frankly – what you did was purely out of ego and the wife is the one who got hurt most.
And he no doubt slept with his wife all the while.
He also told many lies to you – because i can tell you – he still wanted the best of both worlds.
Just move on – but dont look for people to justify it for you. There is zero excuse. Where was your sense of feeling for others ? Where was your thoughts for his wife ?
Once your ego was getting stroked – and whatever else – you carried on.
I wish you no harm, but I wish you to see the hurt has huge concequences. Huge.That woman may never trust again. Please be aware that every action has an equal and opposite reaction.
