Most importantly, treat him right. Treat him like its the precious thing you ever have. Get your time altogether for him. Even if you busy, make him understand how much you didnt want to neglect him. If you're near, make time to meet. Not always, because it will irritate him. If you're far, dont missed a chance to make him feel content. He may seems not much to share daily so just spill out what you think in your mind. Keep yourself to always asking him about his whereabout. Be there for him, because you'll never expected what the time he will need you the most. You would regret the time you're not there and he needed you. He may not a douchebag full of cliche love stories, sometimes he would look just as silly you would think how on earth that he can be yours. He love surprises. He loves singing. There will be time where you needed his lullaby to make you fall asleep. He would probably asking you few times whether he's handsome to you so always drop a few compliments here and there so he wouldnt feel insecure being with someone as beautiful as you. Dont ever be a queen control to him, especially when he's with his fams, He may few times pick his family over you so please be understanding. Dont be a 'pushy', he hates that the most. Leave goodnight and morning texts. Make him proud of you. Dont ever betrayed his trust and he will love you more than you would love yourself.
Whoever you are out there that gets to call this boy yours, cherish every second of it. Because it will be one of the best moment of your life, just like I had.
