Sing your favorite songs together
Take long drives
Be considerate of each others thoughts and feelings
Share your thoughts and feelings
Be honest
Don't use their past against them
Schedule at-home date nights, cook dinner together and then cuddle and watch a movie
Buy flowers
Never go to bed angry
Kiss in the morning, before bed, and as many times as you can in between
Hold hands in public
Always ask them how their day was, and honestly and sincerely listen
Laugh
Love with an open heart
Don't be afraid to take a chance
Understand the difference between needing them and being needy
Dance along to the radio
Have some alone time away from home (cabin on the lake, camping)
