The red flag for me is that he wants to live with his parents AND you.... asking you to not only move away from everything comfortable for you, but to move in with HIS parents? Now that's attractive. The other red flag is: you don't seem happy. You made it seem like you are willing to settle for less because you don't think anyone who is healthier will want you. That's distorted thinking. I know plenty of people with mental health issues who have married healthy partners and are happy. Don't settle for less than what you truly want in life.
