It's a possibility. The coaches will work with one of you at a time, or both together. You can click over and read up on their credentials through the Telephone Coaching link at the top of the page. If you want to explore that option, I'd schedule a session with a DB Coach yourself first to talk over this whole idea of the Coach working with both of you, your H not being sure, etc. He will need to feel comfortable that they will be fair and objective, that they won't simply pressure him to stay in the M 'because that's what they do', and talking to the Coach may help you find ways to convey that message in a manner he'll be able to hear.
Another tactic is to schedule one session but let him go first, by himself. That way he won't feel you've contaminated the waters, so to speak. They have an 800 number with someone you can talk to if you want more info.
I absolutely do not mean to pressure you to do this - it's just that it did help me and the DB Coaches seem like they might be better than many other therapists at not deciding at the drop of a hat that the best thing they can do is help both of you 'move on', ya know?
I've only had two sessions, and they made a huge difference for me. My H has never talked to them, but I may suggest it here shortly.
The trouble with having an open mind is that people put things in it.
