I hate to be the voice of dissent but I would exercise caution: You are asking us many questions and seeking input from a Buddhist perspective.
This will be of absolutely no consequence to her. She will have absolutely no notion of your interest in Buddhism and to be blunt,. it sounds, on the face of it, as if she never would have. In fact, she will either find it irrelevant, or use the globally-distorted image of "what a Buddhist should be" against you and condemn you for not being infinitely peaceful, loving, calm and open-armed as apparently all Buddhists Must be. Mustn't they?
One phrase: beware the Emotional Leech (or Vampire, as they are sometimes referred to.)
She's an emotional leech/vampire.
Look it up - they drain your emotional life-blood, invade your every thought and dominate your energy until they sap it.
There is a remedy, a 'silver bullet', a 'stake through the heart'.....
Counter every depressing negative thing they say, with an equally (and more so) UPLIFTING and POSITIVE thing about yourself
Then immediately change the subject to what you want to talk about.
I've 'killed' two emotional vampires this way.
And they do this themselves - they extract themselves, because they can't stand the bright light!!
There's a difference between Tolerance, and Acceptance, and there's a difference between Idiot Compassion, and Wise Compassion.
Tolerance - putting up with something, even though there are judgemental limits. Like religious tolerance. Hindus are welcome to live in the UK providing they do not burn their dead on six-foot-high wooden pyres, next to a river and chuck the remains into the water.
Acceptance is understanding that certain people have certain mores, values and opinions, and even though we might not agree with them, we vow to not argue or contest these, but see them as part of that person - 'warts and all' - and still reach out with a helping hand, regardless.
Idiot Compassion Supports somebody, but removes their own strength to work through the problem themselves. we do the donkey-work for them, then wonder why they're still falling flat on their face.....
Wise Compassion enables a person, with our support, to stand on their own two feet and find a skilful solution to their own problems.
If any of this rings alarm bells: Feel free to PM me.
