Seems sensible, and there's no more you can do. None of us are here voluntarily, and that means you. Bless you.
Mind you, small story. My mum had a dog when she was a teen, given to her by her dad. She loved that dog more than anything. Now, my grandfather was actually a really great person, but when his life crashed in on him for the fourth time, he became broken and a drunk. He did a lot of crap in those days. Of course he became unemployed and my grandmother had to carry the family, and the little money they had went for booze or cigarettes. This was after the war, so living conditions were tight anyway. He also became violent and extremely verbal, so they were evicted, which is funny, because it had been our apartment complex before the financial difficulties. The only place they found refuge wouldn't let them keep the dog. So, they brought him to an animal shelter. Ultimately, everyone agreed that he wouldn't bond with anyone else and thus, with a heavy heart, they had him euthanised. He was only six years old.
A year later they moved into a new place, one which would've let them keep the dog, but the damage had been done. My mum never forgave him for that and the relationship stayed frosty for the rest of their lives. He died some thirty years later, alone, and with one leg amputated due to health issues. Ironically, I was six at the time and never met him.
For what it's worth, I think it is the right decision and all the best to you both.
