Re: Fiancee.
I second TLK…for once. 
From an Islamic perspective, verbal communication with your spouse to be is fully allowed and encouraged, so long as the subjects are “ma’roof”, i.e not lewd or inappropriate.
From a non Islamic perspective, i understand that people try to break contact before the marriage to enhance the excitement and anticipation or whatever… and in fact i tried to do it; up until then, i had seen/talked to my hubby for years before marriage almost everyday… so the “not talking policy” naturally lasted all of 6 hours… you can say i have no sabar, but when you’re that involved in each others lives and seek solace in each other, it’s pretty difficult to cut that person out… especially at a time of serious stress (the wedding) where you’re both probably going through the same emotions…
Do what feels right for you. Try the no talking policy and see how it works out
