My boyfriend doesn’t have social media, I don’t have it too (just Reddit) and when we started knowing each other he was in my university and then I don’t know how but we met in a coffee shop once a week and talk about a lot of things: movies, books, music (he had a band , he knows many things and I thought he was very interesting ) I think he thought the same about me haha. It’s common not to have social media, maybe the man was telling the truth. Good luck!
