Why does he want to still pay my bills if I'm not wifey material?

My Fiance and I got into a huge argument. I can admit I was being disrespectful to him but I felt he was pushing my buttons. Normally I don't react to him but he really pissed me off. He said I am not a wife and called me dumb. The next day he sent me some money to pay some of my bills. He did not acknowledge the argument. He just asked if I need anything, I apologize for my behavior he accepted it. I do want to address the issues but I'm not sure if I should since he accepted the apology. I know he will bring this up again I don't want to sweep this under the rug. Why would he pay my bills if I'm not a wife. Also should I bring this up later or let it go?
