I'm here with a H that has PTSD ( from the war) alcoholism, and MLC. He is seeing a psychiatrist only because I forced the issue with his command ( he left me over it) and I have no idea if it's doing any good as he has taken up with a girl 15 years his junior who is probably undermining the whole issue.
SO, If your husband is willing to see a specialist, I say find one somewhere, anywhere, even if you have to travel to see one. Start with the MD, work over to a spiritual counselor, and then to a psychiatrist or psychologist. Be proud that you have a spouse that recognizes a problem and is willing to seek help. To to any lengths to find it. (((HUGS)))
