We can only offer our own viewpoints, for a more specialized observation I would recommend some kind of family or individual counseling..
Too many people are willing to just throw a marriage away when the spark fades (if there ever was a spark) but marriage is much more than that. It is a sharing , a togetherness. without it you will both be miserable. I would suggest acting one way or another , getting counseling or getting out as soon as possible to save anyone in the family from further unhappiness. Life's too short to waste it complaining about your marrage on a discussion board that has no qualified therapists..
Go to a professional for your help.
If you can't afford it call the United Way, they counsel on a sliding scale.
Snoozy...who also wants to say nice to have you on board...and I only mean to help.
