DH's friend having an affair and I know

[Hazydays7]

Just wondering where I put my thoughts in this situation, anyone been here?
Dh's found out a while ago that his friend is having an affair. They have a friendship group of 4 and drink together so DH says his friend has said he's been unhappy in his marriage for ages and met someone else through OLD!!
I've kept quiet for ages but I know his DW (not close friends) . What really got me about it was the other day on their anniversary his DW posted a wedding picture of theirs on her FB account. It had all the guys on as well (who know) which really made me cringe and realise just how cruel this situation is. I'm not sure she would do that if their marriage was really unhappy?
I felt so sorry for her when I saw the picture, I can't say anything but feel very uncomfortable. What should I think?

Strangely, it's also making me think about dh and his part and I'm not feeling too good about that at the moment and he knows it.

This ^^ 100%

The cheater and his friends are just fine with it. He knew they'd be fine, hence he told them he was cheating.

I would not conform either, but you need irrefutable evidence before she would believe it anonymously.

Women live in denial.

I had a friend who had a cheater of a DH. People told her he was hand in hand with OW , dancing in nightclubs etc.. and she just said - unless she caught him in bed with another woman, she wasn't going to believe any rumours.

So people stopped telling her ... and guess what .... she eventually caught him in bed in her house and forgave him.... until he later left her anyway.

Bottom line ... unless you know the OWS name.. where she lives or works or any solid proof... she is inclined not to believe it.

Although a tip off with little info got A BW I know into investigation mode and then she had hard evidence.

I'll send you a PM.
