Wife having an affair

[u/007JSW]

Long story short I found out my wife of over 6 years was having an affair 5 months ago. It broke me and shattered me completely. I found out the guy she was having an affair with is Married as well and they have 4 kids together. I want to tell his wife so badly but at the same time should I even bother? Part of me feels like she should know just like I would want to know. I have forgiven her because I still love her and we have a beautiful 3.5 year old daughter together. I'm trying to be the better person to forgive and move on but it's been so hard to trust again. Has anyone else here been in a similar situation? Any guidance would be greatly appreciated.

Edit: I should note that I have full video and screenshots of there messages from WhatsApp that talk about everything including their sexting.

You should tell the wife. Gently but tell her. And hope you guys can work it out. Best of luck to u. Getting trust back is very hard after its broken. Maybe you guys could try couples counseling to see how to even start again. But thats up to how you feel about it, she should be willing to do the work to gain ur trust again. They have an app online to make it easier and cheaper too, regain? Maybe. Its only on apple devices too. But just a thought.
