A mutual friend of ours lashed out at W for some of her recent actions.
There's an implication here that you've been venting to said friend about your W's actions. How else would he know what her "recent actions" were? This is exactly why we should NEVER discuss our sitch with mutual friends and family, because they always butt their heads in thinking they're helping. But usually it does way more harm than good. I had to go find a new circle to discuss my sitch with, I reestablished friendships with three friends that I had not spoken to in years. None of them had any connection with W, so I knew it was safe to talk to them. Then to mutual friends and family, I just talked about GAL stuff, how happy I was, how great things were going, etc. If they asked about W I would just say that we were getting along fantastic but that we both were taking time and space to decide where to go from here and that is ALL I would tell them. If they pushed for more I would change the subject.
