I have a habit of answering questions with stories, so here's my story to you.
Once upon a time, my in-laws were 'mentoring' a young couple at their church. Every time we'd go and visit the in-laws, my m-i-l would start talking negatively about them. She would always tell us that she actually said to her "Your house is such a mess, if you don't get it cleaned up, I'm going to call CPS." and "If you were my daughter, I'd take custody of your kids". Things like that.
I felt badly for that couple because I fail to see how that is 'mentoring'. I don't think that anyone who is helping you should talk like that about you behind your back (or to your face, for that matter). It seems like they're trying to help you so they have a sense of personal achievement.
Just my two cents.
Good example. Reminds me of an aunt of mine (who by the way I will not be around anymore). She wanted to always be known as the good samaritan, and don't get me wrong, she would help people - but like your in laws it was always with gossip behind the person's back she was helping, and she was very controlling, therefore in order to get her help you had to abide by her domineering ways.
So it's kind of six of one, half a dozen of the other. Do you choose to remain around someone for their help and stay victim to the gossip and/or domination? I personally chose 'no', she got on my nerves so bad I couldn't even visit her anymore. I wish her well, but i don't choose to surround myself with negative people who want to control everything I do to suit them.
petitegirl only you know if her help is worth knowing that she will malign you behind your back. If you need the help that badly then accept it comes with a price. If you can do w/out her help, i'd suggest just not being a part of her life to any serious extent. People like the woman you describe are usually control freaks. They get pleasure out of helping but often the helping is a form of controlling and very much comes with a pricetag.
