I’d arrive 10 mins late, over dressed, and wearing NEW aftershave - not the one she buys for you or you know is her favorite. I’d be confident, happy and even a bit flirty with the waitress. Tell your wife all about your gym and exercise program, and all the GAL things you’ve been busy doing. Tell her about a holiday you’re planning - like a singles cruise, or a hiking or skiing holiday. And then I’d leave early “Thanks for dinner, glad to see you’re so happy! I’ve got to run, I’m going to watch the baseball game with some mates!” And then leave. Do NOT wait for her to end it.
This is great advise. It is the bare minimum of what you need to to.
The key is not being the old you. You are now a more happy, confident, attractive, sexy (and not boring) version of you. Do not be cocky about your GAL. I lean more toward the mysterious, ie not too many details. You want her wondering what you are up to. Give too many details and she does not have to use her imagination and loses interest.
If you are normally focused on her, definitely give attention to the staff. Small talk goes a long way. Can you make the waiter or the busboy laugh? The hostess? Another customer waiting to be seated?
Don't be boring.
Good luck! We wish you well.
