'My Heart' is a good poem. But as you progress as a writer, you want to try to avoid cliches and use more creative metaphors and smilies. For example, 'every time I see you, my heart melts away' could be written 'my heart melts like a lit candle when you grace me with your Romeo-like presence' or something like that. But it comes with time. Good luck!
You said you loved me but what do you mean treating me like crap acting as if I don't know a thing My friends tried to tell me but I didn't beleive I wanted it to be perfect just you and me but I was wrong
