I believe so though I am not suggesting that's easy for you when you have previously enjoyed chats and friendliness with her. I had a female friend who was lovely to me 1:1 and fine when men were present. But if we were out socially with an all-female group she made snide little comments while I was speaking in what I could only interpret as an effort to undermine me. Who knows why people do what they do half the time? Sometimes I feel healthier when I spend less time on the why and simply focus on my own peace. That said, I think these threads and discussions can hopefully provide solace and catharsis when we are struggling with interpersonal issues
