Past cheating history !

About 3/4 years ago I use to game a lot , especially online , as I am female 💁🏼‍♀️I use to get a lot of male attention ,even though I was 15/16 years old (very wrong I know😳) but there was this one guy I use to play with daily and things got closer and we added each other on social media and so on ... he was in like his middle 20s and it was the definition of wrong 🤮 , anyway he sent me dic pics and videos of him ..... , what makes this situation worse is he had a wife and 3 kids , I didn’t tell anyone as I didn’t really know what to do and as I was young I did like the attention but I can’t stop thinking of how I should of told his wife , they are still together now and he has just popped up on my feed confessing his love for his wife 😒 and I can’t help think what if he is still doing this ????

Do I say something now or is it too late ?

I know I should of told to begin with but I didn’t think too much as a young teen 😞
