Welcome!!! I think it might be important to realize that his moods are his not yours. As co-dependents I think we just naturally want to fix what seems to be wrong. Is it possible he uses his moods to control you some how? Step back from his mood and let him wrestle with it don't let his mood be your problem. If he is trying to control you with his mood if he sees you not responding that could change things.... No matter what if you stand back from his mood and let him own it I think you will find yourself being more at peace.....
I hope to see you post more I would be interested in knowing why an alanon meeting brings you to tears......(((((((((BIG HUG)))))))))) for you.
