What do you do? This person in dh's family is seriously sabotaging our relationship with one of his parents and some other extended family. They do all sorts of passive aggressive hurtful things to us but they have painted such a masterpiece that when we say something about our ill treatment they play the innocent victim. The lies they tell are not huge whoppers but more omitting of crucial facts and vagueness. I am so upset about this right now. It is sickening to see that they have ever so cleverly pitted people against us for no clear reason other than to be the favorite. We aren't perfect people of course but we haven't done anything to warrant this type of behavior from anyone. We've tried talking to this person and get told we are attacking them. We walk on eggshells because any little thing we do they view as an attack and the whole family backs them up. We've tried talking to the parent that just doesn't seem to like us all of the sudden and they act like everything is fine but it's clear it's not.
Some events transpired today that made it clear to me that for the past couple of years, tied to one incident, this person has been slowly working on blacklisting us from the family. What can you do?
