If you were married then it sounds like you will require a divorce in order to remarry. You also have children and therefore custody, visitation and support of the children will be some of your issues.
People who marry under age usually do so with the permission of parents. You would need grounds if you wish to try for an annulment. However, you do not require grounds for divorce.
