DO: Set aside specific "date nights" for you and your partner to be together.
Again, this may seem self-explanatory. But, many people simply don't make time for one another. Life gets too busy and they forget to enjoy a night out together. You need to make sure that you have those times in order to reconnect. So, shut off your cell phones, get off your computer, and spend some time together. It'll be good for both of you.
