First of all your rhymes are quite predictable, I really don't understand why you write rhyming poem if you don't have any original rhymes in your mind, I think here they were typical, for example when you started with -apart- I knew that you will rhyme it with the word -heart-.
I also don't like the fact that you don't have full stops so it is quite hard to follow your message. And to me most lines don't have too strong connection between each other, also you started each line with capital letter which left negative impression on me, cause if you use punctuation you should know when rhythm of poem should be stronger and when to slow it down.
Sorry if I sound harsh, this is just my personal opinion, I don't want to offend you.
You expressed emotions on good way just little too obvious for my taste.
