When someone dont love you it hurts

The moment I wrote you that letter telling you I loved you with all my heart you walked away and didn't care.
But all I wished for is for me being in your life.
All I wanted to do was cry and cry and tats what I did. I wonder why you had done this to me and then you asked out my bestfriend. I don't understand I never did nothing to you. But you know what's left for you. REGRET!!

I'm sorry my people for not making this as a poem but letting out my feelings is a big relief. Hopefully this will never happen to you. All I want from you is to please give me advice!
