OP, you are now facing the band of MNetters who think anyone should be able to do anything, however anti-social, if they have an addiction, small children or mental health oroblems and that anyone affected by it and concerned by it is entirely unreasonable, probably a fascist and should shut up and put up or even embrace it as part of living in a socially diverse society.
YANBU, not at all. I say that as someone who found themselves living next door to an addict and who works with families where there are often addiction problems and sees the problems they cause their children and neighbours.
My neighbour- where I lived before this- moved into the house next door when I had lived there for two years. Initially he , plus his wife and 2 small daughters and two cats seemed absolutely normal although neither of them worked and he looked sullen all the time. Within a month I started to hear rows which were all him shouting and punching walls, then there were violent rows where he was attacking her in the night and the two little girls were in their room singng together( presumably to block the noise out). I called the police every time and they took him away but he was back within a couple of days and there would be a week or so of calm and it would start again. I rang child protection and social services because of the children.
Then he started appearing in the street absolutely off his head on drink and drugs, sometimes in his underwear, often shouting abuse at my house window from the front garden and the same with the neighbour on the other side. Then the cats disappeared- his wife later told me he killed one kicking it after it had an abdominal operation, and the other one moved in with a couple higher up the street where life was safer for it.
Then needles and smashed bottles began appearing in my back yard, I actually saw him from an upstairs window standing throwing them over the wall and laughing to himself. The neighbours on the other side had small children and were beside themselves. Presumably his own poor children lived in the same danger from him. Police 'had a word with him'.
There were arguments in the street with dodgy people who came to the door, banging on it and refusing to leave and some ended up with fights.
After about 8 months of this, the police arrested him when he attacked his wife so badly she was hospitalsed for two days. She and the children left and we were left with him. He then burgled my house and was arrested and bailed and still I had to put up with his abuse. Some of my belongings were found in the house.
He just disappeared one day and we never saw him again - the police told me the family were well known to them and to social services. I spoke to his landlord a number of times during the time they lved next door. He knew exactly what he was like but it was easy rent as it was paid for by housing benefit and he only got annoyed when he saw the state of the house after they left. There were urine soaked beds in all the bedrooms, urine soaked carpet in the kitchen next to the sink, smoke damage on the cooker and walls in the kitchen where something had caught fire, a plate sized burn in the sitting room carpet, holes in walls, broken doors, glass and needles lying around, shit and toilet paper piled up in the bath and a blcked toilet.
When I think back now, I really should not have called the police, child protection, social services, the RSPCA, environmental health. I should have just put up with it all and let him get on with it. Infact I should have given him money then he would not have been forced to burgle my house to get money to feed his addictions - he had a right to live as he chose. I should have just put up and shut up. I was a fascist, looking down on him, thinking of me before him, interfering, snobby not
I hope I made his life even harder, he certainly made mine a nightmare. And this was a leafy street in a nice area.
YANBU at all. Addicts are essentially self- indulgent, selfish people who don't care about their impact on others lives. That is how they ended up in the grip of an addiction in the first place.
