I am sorry that you are going through this. I understand how hard it is to live with a pill abuser. My RABF was also addicted to pills. It is difficult for them to stop, and they need to have a recovery plan in place. Even when they stop, they can relapse which can be hard on the addict and the family. Has you AH reached out for help? Has he gone to any meetings? Has he seen a counselor? It sounds like he isn't much help to you considering he doesn't have a job. If anything, he sounds like he is an extra burden on top of you having to deal with the children. I don't think it is too much to ask him not to smoke pot. You have set your boundary. You should be allowed to be comfortable in your home and have boundaries for yourself. It sounds like he wouldn't be able to help you buy a house anyway. The fact that he is unemployed would not help your credit situation. If anything, he may be borrowing a lot of money and not paying it off. That could make your credit situation worse.
