Hi Peter, I'm sorry to hear that. Ah - more limbo and another reason for you not to upset the apple card. Your W wants time with brother and Mum without you pressuring her. You know that after this there will be a new reason and more limbo don't you?
Your W isn't interested in having a good M with you just now. And likely you are in for more of the same if you choose to continue on your current path. I don't think she will wake up unless there is a significant change.
