That's another thumbs up 4 U 2 Honesty, a church can be an excellent resource for socialization, as well as getting acquainted with hearing the word from a different perspective.
I was blessed to have been able to go to a marriage retreat. A kind of holiday away from the entire world where couples from all over the country would share and fellowship, much like our assemblies were. They were Bible based, faith based groups, non denominational, non threatening, with scriptural discussion regarding the marriage arrangement, why it's so difficult to maintain, and what you can do to get yourself on the right track, with Biblical, as well as practical instruction on how to get it accomplished.
Quite honestly, if we as witnesses were able to get together with similar concentrated energy, dealing from the standpoint of the husband and wife alone as a unit first, as a community, and not a lacsadaisical shepherding call like many couples would receive, I believe the rampant hidden unhappiness that exist among couples in the Kingdom Hall would be drastically reduced.
Though not married to a witness, they had some of the most profound helps and assistance for repairing even the the worst witness marriage, mines was saved because of it, and I am much richer emotionally because of it.
