She arrived today. We established boundaries and rules. I had to tell her to stop saying Thank You! She thought she was going to have to live in her car.
I got home from work tonight, and on the counter were flowers, a bottle of wine, and a very sincere card, (as well as a bag of Cheez Doodles! She remembered!) She even did some cleaning!
She knows this is just temporary, and I think we will be fine. I was concerned when I first made the decision as I have a tendency to agree to something before really thinking it out, but in this case, I think I did the right thing.
And her pets are adorable, quiet, well behaved, and as far as the suggestion of me taking the dog, I would hate to separate them as her family has already abandoned her, so to take her beloved pets away, would be cruel. You can see how much they love her. Even her cats seem to protect her instead of being aloof. Besides, it would be cruel to the dog. I'm away from home 10 or more hours a day.
Thank you all for your suggestions, and I will stay on top of things. Like I said before, she is like my 3rd child, and as she said in her card, "blood is not always thicker than water, love is."
