First of all, I must thank you for your Valentine's gift even though you knew that I am leaving you. I don't mean to hurt you, although I have already done to you. It's all my fault, I must confessed and please don't blame yourself, you are innocent. I am not going to defend myself in the letter because I am guilty.
I just want to tell you what my decision came out. When I came back from Taiwan at the end of last December, I was waiting for the good news of my job promotion, but the results made me totally breakdown.
As I mentioned it before, I worked so hard even my supervisor promised me, but got no return from the company at final, just because of the qualification and not my ability, I cannot stand it. And that's why I decided to further my study so suddently. It's the only thing I will concrate on it in the future and nothing else more. So, you are my sacrifice of studies, and I am really feel so sorry.
You don't have to pity me for I am guilty. But I hope you can understand my present situation is unstable, and I still have so many problems ahead of me now. How can I get along with the other things such as falling in love and taking care of a girl who is so far away with me.
As time goes by, I think you will forget such a heartless and selfish boy as me. Now I am really so down then I cannot accept anyone's love and just want to be alone to face the future.
At this moment, I'm not asking for your forgiveness because you don't have to. What I can say again is 'I am sorry', although these words may mean nothing to you at all.
Lastly, may I ask for your favor to forget me. Don't give me any reply, in whatever way or through any channel. So, please leave me alone, I sincerely beg you.
