Yoda, this is YOUR home, and you're not 12 years old anymore. I'm not suggesting you be disrespectful to your DAd, but if he does come, stand up to him. You do NOT have to accept disrespect. The way I think is this -- I EXPECT common respect -- I expect nothing more, but I'll ACCEPT nothing LESS. Your Dad has no RIGHT to continually degrade you and ridicule the way you live. You're an adult now -- In fact, if he has that right, then YOU have the right to ridicule the way HE goes thru WIVES!!!
It would be better for you if he didn't come -- to have you trying to clean the house certainly isn't good for your asthma! So try to get ahold of him and tell him not to come.
But if he does, don't take the disrespect without saying something. He has no right to treat you that way, whether he's your Dad or not. You don't treat HIM that way, and what's good for the goose is good for the gander in my book. God bless & please take care. Hugs, Lee
