"I’m not that I’ll be able to last very long." - Did you mean to have the word 'sure' in here?

"Sure, other guys have come along, But none of them are quite like you." - You're switching tenses here choose past or present - not both.

"I hope when it does, you’ll be there, forever to stay." - No comma after 'there.'

Try to get all your lines to have the same number of beats - or at least have their be a pattern to it. This is so irregular! ~*Mettie*~

Another poem I can relate to! It's really good! Can you post some stories?

Hey, it's good. Great job. Keep writing.
