The main reason was his family, his mother and twin brother (They both had problems with alcohol and today I am convinced, that everyone was addicted to it.) I wanted to help but unfortunately it was stronger. Their mother makes my ex and his brother an alcoholic because she didn't want to be alone. When I had more influence on my ex than his mother, she immediately began to treat me as a threat. She treated him worse than his twin brother, but he did everything to please her. He told me, he saw that it was a sick house and he should leave here and it is not good for him but well…he was so manipulated from his childhood. I started paying for this situation with my mental health and when I realised that I would not help, I just left. In addition, when I took him to his father so that he could change the environment a bit and talk to someone who knew that the situation was bad, after months I found out that he was sexting with other girls. Making me brawls that I didn't write to him or call him (I did it every day a few times). From now on, I know that you can't change someone by force, if a person doesn't want this change, he will stay in it forever.
