Do I reach out to her?

If I were her, I would absolutely want to know. You may not have been the first, and if he is having unprotected sexual contact with others, he’s putting her own health at risk.

I would reach out but only if you have proof and I would also make sure to do it in messages not in person because people can be crazy (I’ve watched to much deadly women for ID) 😅 if you do go in person make sure it’s a public place and someone knows where you are and who with.. and make sure it’s clear you were not aware when this started but after things weren’t adding up you snooped and found out he was married and just let her know like you aren’t interested In him anymore but you think she has the right to know in case there are others or have been others

I understand not wanting to bring harsh news to someone you don't know because it will shatter their world but you should let her know and give her proof if you have any. Not telling her and cutting the man off is only allowing him to continue this sneaky, unfaithful behavior with someone else. What if he contracts an STD and gives it to her? What if it isn't curable? Would you be ok with knowing you could've warned her of the potential danger her husband is putting her through but decided not to because you felt uneasy? He doesn't deserve her or you. Soery this happened to the both of you.

So are you? Keep us updated.

As a wife I would want to know. 🤷🏽‍♀️

Deffo tell her!!

If you tell her keep in mind that most of the time the other woman gets most the blame even if she didn't know and the wife will more than likely stay with him

Tell her. I believe it is your place and business because you may be the only person who will ever save her from this dirtbag. Then it’s up to her if she wants to stay.

Tell her, she has every right to know what is going on, for emotional and health reasons. I understand you are in a very difficult place right now but the best thing to do is to tell her the truth.
