I Don't Care (feat. Adam Gontier) (US/Revised Version)

I think it means that no matter how hard he tries for her, she will not listen or give him a chance. like no matter what he tells her. How he would do anything for her and she just will not give him a chance. she wants him to change for her but wont do anything for him or have anything to do with him until he does. so he's saying hell with it
