Loneliness is real, even with a family

I love my wife and kids but I feel so alone. Don't have buddies to hang with anymore - everyone moved or had their own stuff. Work friends are work friends. Wife is mostly focused on the kids. I'm just existing in this house with people and feeling completely isolated. It's weird to feel lonely around three other people. Joined a dad group at the community center but I feel awkward being the new person. Does this get easier?
