I think she needs to feel free to make choices about her life. If she feels traped and sees no way out of a miserable existence, then it could cause her to be more depressed.
Except that this is standard play from the WW/WAW playbook. Almost all of them say "I feel trapped" especially if they don't get their way with the LBH leaving the house, the MBR, doing the D work, etc. No one can make her feel trapped except herself.
My wife played the "trapped" card early on. Even started saying things like "I don't know, maybe I can be ok with it if we sleep in separate beds". I never tried to stop her, if she wanted to sleep somewhere else she was free to, but I wasn't leaving the marital bed.
Either OM dumped her and she is in the grieving process of losing that R, or she is trying to manipulate and control him. Time will tell.
