In the charming state of the US in which I live, my BF has to actually go through the legal eviction process. If someone has clothes in your place and sleeps there, then they have a defacto verbal month-to-month lease. So, the AS of my BF was given an official 30-day notice of eviction. If my BF must move out during that time to keep from being hurt by his crack addicted, alcoholic son, then so be it. But at the end of that time if he does not move voluntarily, then the police will remove him bag and baggage. That is the day when my BF will change the locks.
If this is what you need to do, DO IT.
If he asks for money, NO is a complete sentence.
If you are afraid of him, get a restraining order.
YOU are not responsible for him, his addiction, his verbal abuse, his whining and moaning, his wound care.
If you continue to have illegal drugs delivered to him at your door, YOU WILL BE ARRESTED.
YOU ARE the only person responsible for the state in which you now find yourself. Please take some actions to help you! BE FAITHFUL TO YOURSELF....
