Never stop showing your significant other that you love them.
Send those cute texts.
Surprise them with food, little gifts and random dates.
Compliment them. Be there for them when they need you, whether they want to talk or simply need someone to hold them until life seems a little less dark.
Tell them how lucky you are that you have them; don’t let them think they’re a burden to you.
Make an effort to listen to the music they like.
Don’t hold grudges, forgive them.
Learn the small things like how they like their coffee.
Kiss them when they don’t expect it. Don’t let them go to sleep angry.
Most importantly, listen to them. Listen, listen, listen. You can never do enough listening.
