Oh the friend is a women who is in an abusive relationship, she works for my wife so at the moment they probably spend around 12-14 hours a day wth each other. I've felt since she started to lean on my wife for support that it's been affecting our marriage, I brought it up in the past but she just gets defensive. In the past this women has lied to me about where my W is, but not how you think. It's when my W is somewhere completely known to her and it's maybe getting groceries, but she'll shrug her shoulders and say no idea. She also put herself in the middle of another couple that broke up, she knew every little detail. I've wondered if she has pushed this to make her feel better about her own marriage...
From my experience I would hazard a guess that your W is taking as much advise as possible from people that will tell her what she wants to hear. A familiar ear of sympathy to fall back on. This usually happens when the WAS isnt confident on her decision but so needs external influences to validate her choices.
At this stage it is not about trying to work out why they are doing what they are doing, as they are only reacting to conflicting emotions at this stage which makes no sense nor does it follow any logical pattern.
Its all about you now - If you sense yourself doing or saying something for a reaction from your W then hit the brakes and rethink because you’re the enemy at the moment and giving her further ammo to use against you isn't going to help your cause.
