I Got Rid Of It, But Not Quite!

After 10 years together, the last 3 of which were living torture, I managed to oust the legal one (not without help). He always drank, but 2 years ago he lost his job and his hobby became around the clock. Soon after, he discovered the miracle of Facebook. He began to live in a fictional world of alcohol intoxication and to live as a virtual superman. At one point, its degradation began to become more than visible, starting with the morning trembling of the hands and ending with personal hygiene. Every day when I came home from work, I found the dirty dishes from lunch, an empty bottle and the open computer. Well, I couldn't help but look at what he was doing while I was gone. He started trying to take down various women, exchanged telephone numbers, and even one of them tied up and they saw each other. That was the fun part. After help from friends and relatives, I was able to kick him out of the house in the spring. I had completely forgotten that I had a spare key with my father-in-law and one day I found my house half-empty. Anyway, drunken work under someone else's pressure. I changed the lock. I found a lawyer and decided to try in a good way - to discuss it and divorce by mutual consent. But he did not pick up my phone, nor did he answer via Skype or e-mail. I went to them, he was on all fours, the house with broken furniture, a moldy pot on the stove, empty bottles and butts on the floor ... it was an idyll. Although drunk, he said that he would give me a divorce only if I paid a 5-figure sum .... the argument - because he had bought the cabinets for the kitchen where he lived for 10 years :) A month ago I filed for divorce, he categorically stated that will not sign the summons. Ten days ago, he called me one night with screams, screams and threats that he wanted a divorce immediately. In short, ours found some drug addict (unemployed and living as a nomad with "friends") who settled with them. He wiped it in a neighborhood pub. Apart from the fact that extortion and psycho attacks continued, the amount for the cupboards doubled. She said she would find me and send people to beat me if I didn't pay, and he would personally destroy the house. It is clear that the pot has found its lid, and it is only a matter of time before the father-in-law returns from the villa and throws them away. As for the finale, I'm not afraid of it. He may be an alcoholic, a liar, a complexist, but he is not aggressive. Precisely because of its complexes, however, it is susceptible to other people's opinions. My divorce claim is based on his alcohol dependence. But the reactions lately are starting to scare me. In tandem with the young lady, I don't know what they are capable of. Do I want to calm down, whether to seek help or become aggressive until all this hell is over. Your "Cassandra" :(
