When to Let Go

I raised my son. From the outside, it seems that I did okay. He is high functioning and verbal. He graduated college, has a job, and drives. But some things just don’t change, and I don’t think I can make any difference anymore. He just doesn’t see the value in things that are important to being an independent adult. Financially, he spends all of his money on his obsessive hobby it’s too specific to name here, but it isn’t gaming. I think that would be easier. Hygiene, he needs to be supervised and sometimes won’t comply even then. Clean clothes, laundry, sheets on his bed, he doesn’t see the point. He’s not mean but also not nice. He argues me when I try to make him comply with basic rules. I don’t have it in me to truly kick him out of the house. He would end up living in his car. He doesn’t have any friends and doesn’t care. He sees a therapist and complies with medication. I think this is as good as it will get. I just feel trapped and don’t know how I can do this forever.
