This is a very deep poem pouring out with emotions of hope and love. Love can be more painful that we seem to think and I like the way you described the way she gives you a plastic smile that was a beautiful way of describing ones mask.
The part where you talked about being number one in this fake world really captured me as I can truly relate...
I find that when you love someone or think you love someone they could be completely fake and lie to you the whole time yet you are blind by what you think is the truth....
The hardest part is to continue this journey knowing that they might just repeat goodbye and you lose a bit of that hope time and time again! Keep strong and know someday someone better will come your way!

overall great poem!
5/5 from me!
