Is there something specific you want him to do when you are upset in that way? It sounds like he tried a few things that weren't what you wanted and then gave up trying to figure it out -- which may not be ideal, but it's understandable, in a way.

The fact that you are working three jobs and supporting him while he isn't working at all is kind of a huge red flag to me. Is he making an effort to get a job and support himself?
