To help you figure put who you were and are today, make a list of activities/hobbies that you were interested in then and now. Plan some day trips, join groups that you may be interested in. Plan activities with your kid(s). Do not sit around and wait on your wife. This is your time/journey to self discovery.
You might be surprised at who you become while on your journey.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
