In a group I have every right to be in, one woman is so lovely to everybody else but as cold as ice to me and often doles out a passive aggressive dig. I will admit that this nonsense is in a whatsapp group and I don't contribute too much, but I don't want to leave it either as the other people in the group are important to me and I am not going to just give up on a group of people I like because one woman has decided she hates me 
I haven't done anything to upset her and certainly nothing that would be proportionate to the level of iciness she has blasted at me for the last year and a half.
She told me once that she didn't go to her school reunion because she went to an all girls school, but i am no threat to her because I'm literally the opposite. I'm not trying to win the approval of any of the men, I want the group to be a cohesive group where everybody is comfortable. But this woman acts like I'm something she has to endure. She needs an enemy I think.
I'm her enemy apparently. Is there a way to step out of that role? I've not once reacted to her treating me like a ghost. Never challenged her on it. It does bother me less than it used to and every time she's a bitch to me, I feel, omg, you're a mess (on the inside) so I'm coping ok, Just really curious to know how others dealt with being cast in the role of somebody's enemy.
