H is beneficial in that he can relate to the emotional position he is in because he has been there (and still is to some degree) Something to add to a "what to talk about in therapy" list. I assume your H will tell the therapist, your brother is living with you and about your brothers history.
For the most part, I am staying put in this R because of my brother (is that like staying together for the sake of the children? - lol) Maybe it is, but you have other reasons to stay. Who knows what help the new therapist might bring.
HW, inertia, small signs of improvements, and hope are big things that keep LTR's. going. You know the alternative, leaving will be rough.
If you stayed through 2 A’s and all that mess, give the R some time and see what the C does for your H and the M.
