Very good question, m. (and welcome to the board)
As JWs we used to have a built-in community with built-in friends. Making and having long time friends is hard to do.
Find things that both you and your wife like to do Volunteer at soup kitchens, meals on wheels, etc. Other good people help with those things and you might someone with similar interests.
Take up a hobby, golf, sailing, cards, dancing. Even going to the library and doing book reviews will get you out and meeting new people.
I'm sure there will be other suggestions, but its a start. Making new friends helps with the depression, too.
Good luck and let us know what helps you guys.
Hugs,
Joy
