Yikes, what should I do?

I had a very serious relationship with a man 3 years ago. We lived together and were talking about marriage and we even purchased a home together. We broke up 3 years ago and it ended very badly. He had like a whole secret side to him. He was the odd one of the friends and everyone else were really good people . He secretly did a lot of cocaine and paid for sex workers multiple times a week. He was starting to become emotionally abusive as well. When we broke up he told everyone Its because I was psycho and crazy. I never looked back and just didn’t even care what he was telling his friends and family anyways. Well I downloaded bumble and have been talking to this guy for a couple weeks. We get a long so well but I went to add him on Facebook and realized he’s part of the same friend group! I’ve never met him through this friend group and honestly didn’t put the name together until adding him on Facebook but now I’m worried if he bring me up to his friends, they’re going to say I was crazy or psycho with my ex because they don’t know what truly happened. Should I just let it play out since we’ve only been talking a couple weeks or should I bring this up to him?
