There was also a section in that film about friends NOT being very helpful becuase they just encourage you to give up...I would put yoru wife's sister in that category. You may have noticed your pastor's approach is much more in line with this professional marriage counsellor.

Don't listen to family and friends who tell you to give up...they are just hurting your marriage...SOME CLOWN told your WIFE to give up...who do you think that was? lol
