Thanks for letting us know.
I'm hearing you. I think it's about empowering him to make changes by putting some boundaries in such as even paying $50 a week towards board.
I hear you want to help him out, but I also hear that it's come to a point that he may be taking advantage.
I don't want to tell you what to do, as this is not my place. However, from experience, if people are quite comfortable sleeping all day, watching movies all night, ordering one meal a day, then why make changes?
IF, he had to consider paying a bit of board/rent, had to see to his mental health as part of the conditions living with you, then may be what he needs. Thoughts?
Also, would he be open to go have a medication review? Or be open to you going with him or something?
Things are not working for you at the moment, so something has to change. Boundaries and conditions are so important as a way to protect yourself and him.
I'm interested to hear what you think.
