I want to ask my sperm donor of a father to leave me alone after he found me again.
Not a fan of your biological dad?
He's a weirdo with many psychological issues
Let him know he's not been a part of your life already, so there's no room for him now. I see no problem with your inquiry.
Exactly! He needs to focus on his own loser self instead of contacting me.
You should tell him that then block him after.
