There's some great advice up there. ^^
AllI can add is, please watch this video, a documentary, it will show how the elders are clearly not trained to counsel marriages beyond very basic issues, and why outside help is necessary where physical violence is present.

I'm really sorry to hear of your distress, but as an ex elder, I can assure you we are NOT equipped to deal with such things, and as a husband I can say you SHOULDN'T have to put up with it.
