Extremely embarrassed 😳😳

So I um matched with a guy on okcupid and started talking to him then things died off a bit, we eventually matched on tinder a couple weeks later and then met up the other night. Things went pretty good. He told me that he had a Facebook page so I decided to look him and discovered that another guy I had matched with in November was his brother.... Now I never had a conversation with his brother but I still can’t help but be embarrassed by this. I did unmatch with his brother though and he never mentioned it so I don’t know if he knows. Would anyone else be freaked out if this happened to them?
