You're talking about a big, vague generality that you call an "emotional disconnection." My guess is that there is something a lot more specific and concrete that is bothering you. Perhaps, it feels too personal to go into on a public thread.

It sounds like seeing the therapist, as a couple, was really important to you. It also sounds like you resent your husband's lack of interest and avoiding of continued therapy. Something about therapy seems to have made you feel affirmed. What change did you think that therapy might bring about in your husband that you were hoping for?
