33(M), married for 5 years, 2 years Child, found my wife 32(F)… Cheating with his office car pool colleague. Came to know about it from the Telegram chat I found on my wife's phone. We both are working parents, my parents live with and take care of the child, she goes to job at 7 and comes back by 7.. I go at 9 and come back by 7:30.. so we hardly have 3-4 hrs a day together. She has habit of sleeping early so I take care of the child through the night, sleep it to bed n all…she gave the reason that I am not spending time with her.. and I am not exiting in life… The affair was on going since more than 2 months… The colleague is also married, with a child… My wife even took us all for a joint shopping even while they were having affair. I have confronted her, she said that it will not happen again.
Since that day she still goes in the same car pool, I asked why, she said that she doesn't want to abruptly change otherwise people will suspect something wrong
I also found that she still messages about him, like his health n all.
What should I do?
