i'm not so sure the MC is a bad therapist.
what I see is someone trying to get the two parties involved to see the dynamic.
nobody here seems to have boundries that are defined, actions not words
it just seems to be the same ole same ole, he does what he wants to do, you express you unhappiness over it, but no boundries are in place, even your relationship with your son is up for use.
I would not throw the baby out with the bath water in terms of the therapist, an hour session is just not enough to get a feel.
by telling your husband what behaviors bother you, it gets the ball rolling on boundry making.
Saying that you choose him, does not blame anything on you, it says, maybe we should take a look at this.
It can be difficult for a therapist , with two controlling people in the room, to figure out how to make it flow.
