To tell me brother?

[rollonretirementfgs]

Been stewing over this for weeks...

SIL was caught cheating on my DB with a work colleague about 6 years ago. She was forgiven and they have since had 2 kids,

Husband of my best friend spotted SIL a few weeks ago in a cafe with a man who wasn't my DB. Could be perfectly innocent. Could be another work colleague? No male family members in that age group that I know of. No male friends that I know of, in fact not many friends at all.

Spoke in confidence to another family member, she is 100% adamant I shouldn't mention it to my brother.

AIBU if I go against advice and tell him?

Why is it odd? She was just sat in a coffee shop, it's a perfectly normal everyday occurrence, many men and women sit in quite corners of coffee shops with people who are the opposite sex. I find it odd he didn't go and say hi instead of jumping to conclusions.

I'd think long and hard about this before you decide to tell your DB. Even if it's completely innocent it's not going to be pain free for him to hear this. Even if she's completely innocent this could harm their relationship for a long time. It won't be as simple as DB asks.her and can immediately lay that to rest. It's likely he's going to be thinking on it, worrying about it, reliving it. If she's completely innocent she might be really hurt by DB questioning her, she will feel you don't trust her, that he doesn't trust her. This is something that can do a lot of harm.

If they'd kissed or even held hands or were sat purposeful right up close to each other when they didn't need to be that would be something to tell him. Right now you're considering throwing a grenade into their marriage because she sat in a quiet corner of a coffee shop with a man.
