I was going to suggest that.
Since I have done a lot of self esteem and self respect work in therapy, there is no way that I would allow ANYONE to do what she does to me OR my animals. I would overwhelm such a person and stuff a sock in their mouth before I'd put up with being abused that way or let her abuse my animals.
It's just my current policy and attitude but I'd take such a person on in any way there is rather than allow them to do this to me anymore like it was in my miserable childhood with two very troubled parents!
I suppose an intervention would help but I wouldn't wait for that. I'd do something about her NOW if it were my problem. I'm reluctant to say what, other than it wouldn't be pretty!
good luck,
jim
