I agree that the friend needs to go. But any time I mention it she says she feels more scared and trapped. I recognize that this is something she has to address in IC but she does feel isolated. A mutual friend who she had told that she was thinking about leaving me told her he respects me and so he couldn't help her move out if she decided to do that.
From what I understand my approach should be not to act overly lovey-dovey but to also show that there is a smooth path back if she chooses to take it. The more I disengage the less smooth I make that path.
