Heart broken :(

[apples and bananas]

I've been there. It absolutely sucks! I feel for you.
If you need to leave then tell your parents as soon as you possibly can get the words out. Give them a written notice as well as a brief description. If it's something that you can't help, then that's just it, you can't help it.

I would highly suggest that you re look at staying in your home and having him leave. Or moving him into a separate part of the house... basement maybe? And reside together, but separate, until you have everything sorted out.

If this is your income and you intend to move within weeks, I would assume that would be hard to manage.

Don't ever let someone remove you from your home or business.
