i can fix him
The belief that just because you love someone, you can take a man who has no idea what respect is, and turn him into a prince with just a few tries and a lot of swear words.
'I can fix him. He just needs a little love and a few more chances.'
'He cheated on me twice. I can fix him. I fixed my cousin.'
'He's been stealing from me for years. I can fix him.'
