So my husband is 15 years older than me (we met when I was 21 and he was 36), He's been driving since he was 16. I am not always happy with how he drives but he has improved over the years by maturing. But whenever I say something it's like "he's been driving for so long without accidents so I shouldn't judge his judgment"

Anyways so today another car was overtaking us, sure it was in a place where it wasn't allowed and it was kinda ridiculous, but we had enough space in front for the other car to get in front of us. we were on a road with 2 single lanes, one direction each. (I'm not native to english and we aren't in the US, UK or AUS, so idk how to explain properly so bear with me)

so when the car was passing us, my husband sped up to make sure that the gap was too tight for the other car to squeeze in.

I couldn't see the other direction road because of a van and a truck in front of us, but if a car had come from the other direction my husband would have indirectly caused an accident between the other car, who was now stuck on the wrong lane and a possible approaching car or that car having to move out of the way either in our direction or the other side where there were houses and lawns. I freaked out, I yelled at him to let him back in line because he could be causing an accident. Our road code literally says that you aren't allowed to deliberately speed up to hold someone back from moving back into the line. But my husband said that the other car wasn't allowed to be overtaking there anyways so it would have never been his fault. Then we had a huge argument where he blamed me for never taking his side (when he's driving like this/being agressive on the road)

To put it in perspective : my husband deliberately sped up to close a gap to prevent another car to move in line, which could have caused an accident.

The other car was overtaking in a spot where it was prohibited but when he started, he did have the space to overtake and move back in line.

I am more worried about him expecting me to always "have his back" even when he's being an ass or putting others (or us) in danger. Which is an ongoing issue. Especially when things don't go his way on the road.

I am not allowed to drive with passengers as I only have my permit so if we go anywhere he's driving.
