Is this poem good? how can i make it better?

I really like it you got something going but if you are gonna rhyme create a rhyming pattern in you poem. I don't know if you do have one but I don't see it. I love the story line in the poem. And you really explain the feelings and what this person is experiencing very well. I like it a lot so keep on writing. and i had an idea maybe instead of "or is it another that holds your heart?" I like the sound of this "or is it another that holds your lock and key?". and maybe instead of "who is that girl in your bed?" unless this really happened cause im guessing you wrote this about your significant other so instead of that unless that was true write "who is that girl in the den?" i dont know what to put there really I was thinking "who is that girl in your head?" but you used head right before that soo but change it because saying who is that girl in your bed is a little weird. hope this helps
