Is it just me?

Has anyone else found themselves to feel more aggressive over time when arguing with a narcissist? I’ve been with my N partner for almost three years and I have noticed over the years that I feel increasingly enraged and aggressive when we fight. I get a powerful urge to hit them (which I would never ever do) or break something of theirs. I once kicked their chest of drawers after a particularly horrendous fight which broke both the drawers and my toes. I know this is not a normal reaction and I sometimes feel this same rage and aggression over things that upset me that don’t involve my partner. I end up hurting myself or damaging my own things. I am curious to know if anyone else has experienced this or if I’ve got a separate problem of my own. I’m hoping it will go away as time goes on! It’s been 3 days 10 hours 34 minutes and 55 seconds since I ended it. Send me strength.
