How to keep a girl forever?

How to keep a girl forever.  
Treat her like she¡¯s the only girl you know in your life. I know she¡¯s not your first love but try to act that she is your first and last love.  


A girl demands a lot, cry a lot and get jealous easily. Tell her that you really love her and you will never cheat on her, even if she gets ugly, you wouldn¡¯t.  


Tell her that your heart always beat fast whenever you see her, tell her that you can imagine a future with her, her as a wife and you, of course, as her husband.  


When she¡¯s jealous to a friend of yours, tell her that, that friend of yours is just a friend. When she¡¯s mad at you, hug her. You know tight hugs that will make her squirm in your chest.  


When she¡¯s crying, tell her that every thing will be fine, tell her that you won¡¯t ever leave her, tell her that she can cry at your shoulder and use your shirt to wipe her tears away.  

One thing a girl wants is a gentleman. Carry her heavy bags, open doors for her, remember this ¡°ladies, first!", sing a song for her even if your voice is not that nice to hear, write her poems even if you¡¯re not good at it, you can even try draw a portrait of her and both of you can laugh about it when you¡¯re done, treat her like a princess or a small porcelain doll in your bare hands.  


You know what, even if you don¡¯t do this gentlemanly things on her, she will still love you and won¡¯t leave you but it won¡¯t hurt a bit when you act like a gentleman for a day, right?  


The don¡¯ts.  

Don¡¯t treat her like any other girls when you¡¯re around with your dear, dear friends. Don¡¯t make her cry and jealous. Don¡¯t go messing around with her head and moods. Don¡¯t change her, please?
