Each marriage will survive on it's own merit. If you truly love the other then I believe you will become stronger.It sure is a test. Love is about forgetting self and living for someone else.
I think people try to make you jealous by trying to make you think your missing something. By sticking it through you become a better person than many.I admire and totally respect anyone regardless of gender for sticking with their spouse throughout their trials,and in the end it is one with each other they become. Just an observation from the outside..The real "Survivors"
