what if after your wedding your partner turns into an ogre

I would do everything possible to resolve the problems and make it work. I think that most people find something about their spouse that bothers them after they're married. Sometimes it's a small issue, like that person not turning off the lights when they leave a room. Sometimes it's something big like an addiction or cheating. I think that little things can be worked around and aren't worth getting a divorce over, and even the big things can sometimes be worked on. Sometimes the big things are just too big, though. If you're going to spend the rest of your life miserable if you stay with the person, you may as well divorce and move on with your life.
