Good luck!
My wife and I have definitely settled into the quiet life of an aging married couple. We love it. We both have things to do so neither one of us depends on the other to keep from getting bored. I have my music and my writing, and she has her theater and activities involved with the synagogue she attends. I'm also involved with my church
It's never been an issue, her being Jewish and me being Christian. Formerly we were both Wiccan which is how we met all those years ago. Occasionally we visit our mutual pagan friends from that part of our life.
Our daughter lives in the same city so we see her frequently. Sometimes she and I go to karaoke bars together.
