I have been all over the world, and I hold no journey more precious than my inward journey.
Let me qualify that I am no therapist.
So, the question is, "How do I support my husband".
Number one, I would tell him not to worry about the length of therapy or medication.
Number two, You both need to let go of the past. There is really no room for, he said...she said (conficts between you both, up until this point.) Easier said than done, but my point is to live in today. The excess baggage,get's heavy whether you both know your carring it. (or not).
In my relationship, (if in conflict).I try really hard to clarify what my issues are. Is this just a misundertanding? So many definitions/meanings for the same word/phrase. Sometimes it comes down to how it's said, facial expressions, moods of the receiver...etc (bottom line is... English language is not my friend...clarify...repeat...clarify...repeat...
And then, what is the solution. For example, If you don't like the way I squeeze the toothpaste. Maybe, the solution is simply solved by buying two tubes. Problem solved...yeaaaaaa...!!!
I guess my point is, reducing all other conflict will focus your recovery on healing as a couple.
Stay connected (hug often)
