I heard a great shiur last summer from R’ Reisman and he said that when your wife-to-be tells you that she burned dinner or something else like that, don’t say, “It doesn’t matter, we can just go out for dinner.” or some other similar response. He said that what your wife is telling you is she is very upset that she burned your dinner. When you tell her “It doesn’t matter”, she can hear that as saying it doesn’t matter that she is upset. Very easy hole to fall into and very hard to get out of. Be aware that it’s there. Try to be sympathetic and think about how she is feeling rather than just how to fix the problem. You could try something like “You are probably upset that dinner burned, would you like to go out to dinner?” Show her that you’re trying to understand how she’s feeling and she won’t feel rejected. You’ll probably get tons of other advice. It should be a binyan adei ad!!!
