Thank you all, I am planning on taking the weekend to get the words properly down on paper so it's all clear to them. I know one family will be fine, and will put back up in place, other family, will probably him and haw regarding short notice,( they think I work for them. And am expected to be at their beck and call). And I've already decided in my own mind that if they do this I will term.
I'm an only child so this has really hit me like a ton of bricks. And at this point this family is already on thin ice with me. But that's a whole other story. Lol

Thank you again for all your advice and help! I truly appreciate it.
