So far as I know, my SSPX priest requires couples to counsel with him, personally, before he will marry them. As for teaching NFP, I very much doubt it, but wouldn't know as I'm single and wouldn't dare to ask any couple such a question! He strongly encourages six months' notice. He says he has never yet had a couple split after following through on his program. Before CI folks begin a dispute over the last statement, I may not agree with him on several vital points, but I've never known him to be a liar!
