Fact: Mrs. Bennet shows resentment. Ch3 "Amongst the most violent against him was Mrs Bennet, whose dislike for his general behaviour was sharpened into particular resentment."

Then based on my 8 steps to envy:
1. Admiration of a someone elseīs value
2. Comparison. Conscious of my shortage of value.
3. Year for the value.
4. I try (to copy value, steal value etc) but I am unable to achieve value.
5. Painful feeling for others hapiness in possesing that value.
6. I act: I donīt want to be rich...I want the other person to be poor as me"
7. Resentment: Point 6 didnīt work so now what was a value is a nonvalue. Darcy is not a gentleman.
8. Purpose: Make envied feel guilty and apoligize for his achievements. Destroy the value and the owner fo the value. If I canīt have him I must make him feel bad about it.

IF Mrs Bennet shows resentment (step 7) then she must be envious. But I still canīt figure who she envies among the other ladies and mothers...
