Well, to be honest, both of you need to make great efforts in order to establish the happy marriage life. You should have more time to communicate with each other. Figure the problems and solve them together. If you still find the marriage life cannot continue, it will still ok for you to divorce. You still have several chances to find the true love in the future. Don't worry. Just follow your heart.
