We had an issue with our old neighbour.
Very inconsiderate, late sweary arguments and door slamming, coming around shouting and swearing at mrsdts and me in front of our kids.
Accusing us of damaging their cars, and creeping about taking photos..many more things happened, too many to mention.
Overall just horrid to live next door to.
We wanted to move anyway, we always were going to but they were a significant reason to move sooner rather than later.
We chose not to escalate as we didn’t want to make it more of an issue, before we moved.
I would add that if it is making you unhappy and stressed, take action. I’m not advocating physical action.
get CCTV, report to police, talk to neighbours. It won’t stop making you unhappy if the situation stays like this.
Good luck.
