What is it with all this 'passive aggressive' nonsense? You are painting her as an agressor, she is just another woman trying to cope with various things in her ife which are pretty tough, like the rest of us.
There is no law says she has to like you, clearly you don't like her as you are so quick to label her.
This could be the very moment that things get better and you are asking strangers would it be a good idea to raise painful issues.
Start looking at yourself properly, are you blameless, are your expectations reasonable?
Time for you to be wonderful I think, time to stop with the labels and start with the comforting, you seriously concern me. Isn't you asking whether at a time of bereavement you can raise your own selfish agenda a bit 'aggressive'?
That poor girl, she needs love and support, make sure you go there full of both because you will be storing up troubles for the future if you don't.
