Last Friday I went to a bar and I saw her husband kissing and all over another lady. I was shocked of course, it wasn't his wife. I took a picture and sent it to my husband to confirm if it was him and it was. Later, he smiled at me and I asked if he was *****'s husband (funnily I remembered his wife's name but not his) - he said yes and immediately said they are separated. After like an hour, he came looking for me and start asking if I've been taking his pictures all night. One of his friend probabaly saw me taking that ONE picture I sent to my hubby to confirm it was the same guy who was married and has 5 kids. I know, it's none of my business and it was wrong of me to take picture but I wasnt being nosy or anything. He works with my husband and I was just so taken back to see him "almost having sex" with another girl. 

Long story short, I told him I don't have his pictures and I don't care what he does with his life (basically none of my business). Now it's been 4 days and I can't stop thinking about it all. If he was separated then why was he so scared and kept asking me if I have taken his pictures. And I also start thinking about, if it was my husband - would I want to me informed about his mischiefs behind my back. As a woman, should I tell her or I should just say fuck it! It is killing me know they have 5 kids together and youngest are like 2 and maybe 4 - and just thinking she must have been staying home taking care of babies while he was doing what-not. 

I also know, I don't know their story but would you tell her or just say fuck it ?? 

It is just killing thinking if I was her- staying home looking after babies while my husband goes and fucks around.
