My solution, and I respect its not for everyone, is learn to cook and start inviting people around for weekend lunch/dinners. I think this is more personal and better than heading to bars and restaurants. I find this is a really good way to build a social network and become part of groups. It may be a little intimidating at first, but as it becomes regular, it's easier to add new people to an existing friend group than many new people together. If people get along start expanding to other things. Weekends away or days trips to do hobby x. Bring new people in. Understand sometimes you have to move on from people that dont fit. But overall put in the effort to be the organiser. I think people sometimes forget as an adult you often have to put in effort to build new relationships. It doesnt happen as organically as it did when you were young. There's huge value in it and we'll worth it I feel.
