<human>: Can you provide a brief overview of the text?

Male, 24. I have a fiance, 24. Been together a couple years. She's fun, blah blah blah. You get the drift.

I have told her in the past that physical violence is absolutely never acceptable in a relationship. Abused a little as a kid, it happens, I'm over it. She once punched me in the shoulder - I told her if she did something like that again, i would leave her with zero remorse, and that I expect the same treatment from her.
Cut to tonight. She got stressed about something, I told her to calm down. She got upset, I ignored and started playing video games. She turned off the TV, I asked for the remote control. She said a couple mean things and hurled the remote at me. It hit my arm, but it was definitely aimed at "me."

Right. I get it. I'm a dude. I should suck it up. Whatever. I'm of the opinion that there are no circumstances under which you should attempt to physically harm your significant other.

What should I do? I love her, that much is clear. At the moment, I feel like screaming at her, but I haven't. She apologized and told me that "[I'm] not such a great fiancee all the time, either". Our wedding is seriously in four months. I'm not comfortable marrying someone who thinks physical violence is acceptable. I don't think she thinks it's fine, and I'm crazy about her.. I just... need an unbiased source to tell me something.
<bot>: Fiance attempted to hurt me a little bit, after I've told her that was a dealbreaker. She just lost her temper a little bit, though.
