Should I ask her?

Two years ago, I was seeing a man and we went out on a few dates before I found out he was married.


When I confronted him about it, the conversation got heated & ugly. Needless to say, all ties were cut right then & there and we haven’t had any contact since. Shortly after, I called my Sister and told her what happened. When I texted my Sister a picture of the guy I was telling her about, she didn’t mention OR give any indication that she knew him.


Fast forward, today my Sister post on her social media and I saw the same guy, comment on her post. For them to be connected on social media, when both of their pages are private, immediately concerned me. I don’t want to assume anything, because she may not have remembered what the guy looked like from the pic I showed her. However, them being connected on SM is very strange to me. I want to ask my Sister about this but she’s an habitual liar and she’s known to date married men.


Thoughts?
