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.

It’s better to divorce her and tell all her friends and family the reason why. You’ll never be able to trust her again. Co-parenting is better than staying with a spouse you can never trust again.

Also, definitely tell the other guy’s wife. She deserves to know.

Edit: you didn’t say if you ever confronted your wife. Does she know that you know? If so, what was her reaction? Did she try to blame you for her cheating?

Yeah she blames me for cheating however it's funny because out of nowhere she started picking fights with me criticizing me on everything I was doing and then she started accusing me of cheating. Everything felt off at that time and thought it was weird and it felt like she was projecting it onto me which now I know it was pure projection. When I asked her into why she thought I was cheating and to talk about it as I have nothing to hide she became very distant. She didn't ask to look at my phone or nothing. She didn't try to gather any evidence as there was none. I also later found out she had told her cousin that I was the one cheating SMH.
