Wow. This was a very touching poem. You could have cut off the last few stanzas and made it an amazing poem about the human race and how bad things happen to good people.
I did like the idea behind this- to tell people how you feel because you never know what could happen.
My suggestion would have been to make it a little shorter; I think you went so in-depth to describing what you saw on tv that when you started talking about your love for your boyfriend it seemed like a major topic change.
But other than that, I can find absolutely nothing wrong with this poem. It is definitely better than many of the poems I see that basically just state that they love their significant other, rather than how they came to know that they love them.
