Learn to be friend

Well, i decided to learn to just treat LT as a friend. The fact is a fact, I failed to make her to fall in love with me. I know this is hard. I see quite many similar cases before, most of guys would just decide to never see their girl again. Anyway, i just want to be her side until she can find her true love which is able to take care of her. LOL, seem i need to learn how to lie and act, to keep my true feeling towards her. Hopefully i can do it :)
