That pretty much what this discernment C is supposed to be for. She's confused and on the fence so it's up to 5 sessions for her to decide what path she wants to take. Status quo,divorce/seperation or 6 months of MC. From what I see from her I wonder if she is even in a place where she could even commit to the MC. Even if she did I would still wonder if she's really into it or just afraid to let go of her safety blanket. I think I will ask the C these questions tomorrow and see what she thinks.
She's enjoy some tasty cake-eating. No reason for her to change anything at this point. She's not the one hurting, you are. That doesn't seem to bother her either. Personally I like to knock fence sitters off the fence. It gives you your self confidence back. It worked in my case. I decided I wasn't going to wait around doing the "pick me" dance. That's too degrading and was causing me too much pain.
Your GAL is good but I'd step it up even more. Do whatever you want. Activities that you may have loved in the past but gave up when you married. We all have some of those. Be the best version of yourself you can be. A very attractive version. That will either snap her out of her funk or you'll move on happy with your new positive strong, high self-esteem and have a great life.
