RE the belief I've been taught, in practise for marriage, I think that means if she (or I) are making tough choices & changes(bad things) to preserve a marriage (encouraged by the main 3 monotheistic religions alike), then later (life or paradise) God will give a subsititute (make it happier, children, etc). Does that clear it up at all? Now, I don't think that means being a sacrificial lamb...just reminds one to be patient if you're doing something right/good.
Money isn't the issue for us either, but she has always been that way. Positive - no $5000 credit cards!!
I'm arguing back a lot less, but I can't seem to get out of it yet (!) Excellent to hear you are! Keep that great skill up this weekend~
