I don't want my son to live with me, but I'm afraid to tell him about it

I am a pensioner, I live in my own house. My son is 43 years old, divorced. He does not have his own place. A year and a half ago he asked me to stay with him for a month. I allowed him, but time goes by, and he still lives there. He does not work officially anywhere, he gets by with small odd jobs. He drinks for a week, then takes a break from drinking. He pays me his share of the housing and utilities bills. He eats out of his own pocket.money .

The relationship between us is strained, although I try to remain silent, avoid conflicts. He teaches me how to live, what to do, but he himself does not want to listen about his behavior. I do not want him to live with me, I am constantly nervous, but I do not dare to show him the door to rent a place. He constantly reminds me that whoever goes against him will become his enemy.

I didn't watch something, didn't insist on something, if he became like this. My thoughts are that he will drink himself to death in a rented apartment or will have a disagreement with someone and end up in jail. But it will be my fault that I sent him away from home.

I'm exhausted and test-antibiotic.com I can't and don't want to live with him, and I don't dare to send him away. Maybe someone will advise,What is the best thing to do ? Feel sorry for yourself or him?
