I tried to write you a love poem...

Good write i rly liked the flow

"I tried to write you a love poem but it only end with the words I hate you."

I love the opening line here, that caught my eye. Only thing is "end" should be "ended".

"I tried to talk to you but it turned into a yell. You say you love me but deep down you love her. My smiles turn to frowns."

Well-expressed feelings of all that you are going through.

"How can something so sweet be so sour?"

I really liked this simple yet meaningful question, nice job.

"I put my heart into your hands , you take it and trow it on the floor."

"trow" should be "throw."

"I thought you cared, you said you'd all ways be there. Pain in my heart slow kills me, kills you."

"slow" should be "slowly".

"You see the tears in my eyes and you know you did it, you put it there."

"you put it there" should be "you put them there", because you are talking about the tears.

"I cry for you but your never there."

"your" should be "you're".

"I hate you , myself for every loving you."

Reword to this:

"I hate you and myself, for ever loving you."

"You knock on my door I open it and close it at once."

Place an "and "after "door".

"I don't need you, i don't want you. So leave me a lone"

Capitalize your "i" and "a lone" is all one word.

Overall, 3/5 from me. There were many grammar errors and I felt like this was a rushed piece. There was emotion but a lot of your wording was cliche and not creative.

Take care and keep writing...
