There’s something that you must NEVER do if you are dating: change your looks without telling your partner and/or asking their opinion. I mean, if you are a girl and you decide to cut half of your hair, it might not be something that your boyfriend likes. And the same goes, if you’re a guy and suddenly decide to lose the beard.
When you are in a happily committed relationship, it is important to take care of yourself. However, make your significant other feel drowned to you. Keep the things that your partner likes about you! This will keep the fire alive and will make the life as a couple much easier.
