I agree on that. Even if she hasn't decided for sure to get a divorce, it is good to have the relationship with the lawyer in place just in case they move forward on splitting. She can get some initial legal advice about her options, etc., and help head off any negative legal consequences such as if she gets fed up and decides to move out of their house. (You should never leave the house, unless it is for safety reasons, as it can have legal ramifications.) The lawyer can help her be prepared for all eventualities... just in case. Meanwhile the therapist can help with the emotional stuff. Even if she and her H don't see a marriage counselor together, she might consider seeing a therapist on her own.

Best of luck to your friends, BlueHen, and I hope you can extricate yourself from this difficult position the H has put you in.
