One evening when you can’t get out, plan for your next dates. Create a list of things that you would like to do when you can go out. (Ideally on a shared Google document so you can each add to it as a new idea comes to you.)
Start with places and activities that you know you both enjoy.
Add in some recommendations from friends that you are interested in trying.
Also include some activities related to each of your hobbies or interests.
Be sure there are all kind of options on your list: Free activities or destinations; special evening type places; quick date spots; day trips.
You can also plan for in-home dates.
By just having this list, you will be more excited about going out together. Review the list often. This will inspire you to figure out how to make time for just the two of you.
