I’m going to have to be vague because the details are very outing but hypothetically:
A friend does something to you that really hurts you. You both argue and you are hurt and dumbfounded at what’s happened to your friendship, and don’t speak for a while. Because of friendship groups, you see her regularly but although she is the one that has wronged you - she is the one avoiding you, looks fragile, leaves the group when you approach, and other behaviour that you know is her anxiety causing her to behave erratically.
You know her well enough to know she is reacting like YOU were the aggressor because of her anxiety and you also don’t expect acknowledgment of what’s she done - despite saying to other friends that she knows she’s done.
Yet you can’t bear the situation. You want to let her know that she doesn’t have to worry when she sees you. That though there might not be a resolution or making up of the friendship, she doesn’t have to ostracise herself when you’re around.
Or would you just not bother and leave her to it?
Sorry if this is horribly vague. TLDR: someone wrongs you but is obviously miserable. You’re not ready to forget what happened but would you reach out to them to try and make things easier for them?
