How do I park my love and memories of my wife so that I can get on with my life?

You can't . You have to go through all the ups and downs of letting go. Then when 3 years hit, you can then park the love you knew. Someone told me, when you start recalling and sharing the memories you had with your ex, you are healed. This does not mean you necessarily get back together. And, no more dating the way you have been.
