This poem is an example of irony. I think it shows a lot of hatred, then ends with something very surprising.
I gave you the key to my heart, and you threw it out
I gave you everything I had, and you gave me a pout
I gave you my whole life, and all you did was shout
I spent everything on you, you throw my gifts away
And you cannot give me the time of day
And every other week, you say I cannot stay
Do you really love me, or my money
Do you want the guy that I try to be
Cause you drive me insane, can't you see!?
But I thank the lord everyday, that you decide to stay with me.
