I think this song is a mix of what you both said...
I think it's about a man who's "love" broke up with him. It gave him a ton of anger and resent towards her, and it's slowly taking control of him. Though, when he is around her, it's completely hidden. so "He wants to thank her for the tears he cried, the love she gave, and now he wants to show her what he's kept inside (resent) even if it takes complete control of him"
