Determined, Welcome to DB, I am truly sorry that you have found yourself here; but kudos for finding the courage to do "this." Have you read DB/DR yet? If not, I highly recommend reading one of the two, or both. GAL in your case could be used as a 180; it's doing the exact opposite of what your H would expect...going out after work, having a family member or friends pick up the kids...do something different, and not being stuck in a "cheese less tunnel"
I read in your posts in newcomers, your H is bipolar, are his medications under control? It must be difficult for you going through this year after year, do you have a source for support, family, friends etc.
Please take good care of yourself cdbmod
