I can forget sum1 easily in physical not emotional

Hmm... I really love that person but I can't bear long distance relationship, I'm tired of waiting and loving someone far from me...but maybe after 20 years, I promise to see him in the near future ,and if that day comes...I don't know if that person will still remember me...but if it's not, then...[will see] I left friendster many times and yet no one could stop me [blurry],This message is from the person I really like ,I'm sorry for leaving you again you might hate me but promise me not to forget about me,we will be bestfriend forever! Until we see each other.You easily fall in love which is the opposite of mine.I don't know if that person still loves the so called "ex"...still I don't care. I fell so untouched right now...I'm used in being alone ...alone inside in my dark room...If I forget to tell you just how much you mean to me, I hope that you will remember while your not here with me.
If I forget to tell you that you are my world and more, I hope that you will remember what I am waiting for.
If I forget to tell you I want you in my life, I hope that you will remember that I am always by your side.
If I forget to tell you I love you more than words, I hope that you will remember regardless of the hurt.
If I forget to tell you I am sorry for my mistakes, I hope that you will remember with every one I make.
If I forget to tell you no other can compare, I hope that you will remember the love that we both share.
If I forget to tell you I miss you everyday, I hope that you will remember your absence causes pain.
If I forget to tell you that forever is what I want, I hope you will remember that forever is what we have got. Whether I say these words to you, or wait until you are here with me, I will show you this forever, and these words will have no need.
