Do I tell him eventually ?

So I met someone on hinge and I have a date with him in a few days which is super exciting, but I have this situation where I dated my best friends brother and I’m super close with their family , me and the guy were also friends with benefits not too long ago but we stopped, I will never put my relationship at risk whenever I do end up getting with someone but should I eventually tell him or who ever I end up with ? I wouldn’t want to hide it from him because I don’t want to seem like it’s something to hide about but I’m also scared that it would be a deal breaker, I looked up the guy on fb and he happen to go to high school with my friends closest friends, idk if his friends friends are still friends with the guy from hinge but they know about me and the guys past so I don’t kno what to do
