When two Best friends become strangers 1

In this world of incessant changes, Change is the only constant that never changes. Have you ever been in a platonic relationship with someone who is your complete opposite? I have been with one such person and I am terribly hurt. And the letter below is a personal note of mine on such a friend. 

Hi My Dear Dude,

This is a letter by me to myself about you. I don't have the courage to talk to u on certain things happening for a long time in my life and the feelings in me since u stopped talking to me or behaving differently with me (May be u r not.. But why do i feel so). I wanted to divert myself and I am working very hard to do this in every possible way I could. And this is one of the reason I chose to quit my job soon. I thought things would go well between us and after our last meet(which was a really hard one to deal with), I believed one day(very soon) everything will be alright (but they were not). Things took a different turn. I didn't know the reason about ur strange behaviour and this drove me crazy for nearly 6 hard months continuously where i kept on thinking about u each and every day and I was longing for the day u would talk to me in a normal way (which i didn't feel like happened). I really wanted to deviate my concentration to something else and it was my learning process that helped me engage but that was really hard. Even now i have thoughts on you sometime (unluckily u had forgotten me and I hope I ll commit to myself alone by the course of time). I promise to myself I ll never be close with anyone else like I had been with you. Coz this is the most dangerous heartbreak I had. I believed u ll be a life long friend to me. But we were not destined to be together as friends for a long time. May be these things happen for a good reason. You are so dear to me such that I cannot bear anything harm to u. I must be so strong but everytime i see u facing hardship i break down. We have different thoughts and opinions but u were really a compatible person. Yet we didn't have gud understanding (and thatsy we fight quite a lot of times). And everytime i fight with you I will not be better until i find u had come over it. Its really hard to overcome everything - you, our past, memories..

Dude- You are my best buddy, great friend, love u loads.. Hope we won't meet after I quit.

I always want the best things to happen to you. Love u so much Dude..

Regards,

Ur Dude
