Don't sweat being alone. I used to be very scared, nearly terrified, to be alone. Then I realized that alone is peaceful. You can hear your own thoughts.
You can read self-improvement books and work on your personal growth. You can shut the blinds and walk around barely clothed if you so desire. Sleep late. Let the dirty dishes slide until the next day. Control the tv remote, decide if you want to watch a movie and watch what you want to.
Embrace it rather than fear it. Make the very best of it by using your time to work on you. The investment will pay dividends.
As far as Gifts for your W - give her pictures of the girls, or pictures your older daughter makes, slyly include yourself in some of the photos. Always make it look like you are trying to share your alone time details with her. She will miss the girls and this will be appreciated.
