This situation belongs to a formal marriage relationship. Because of the current domestic civil affairs network problems, if you register for marriage again, it does not necessarily show that you are married, and the household registration book generally does not show the marriage relationship unless you move to your spouse's residence after marriage. But if you don't go through the divorce formalities, you will still be convicted of bigamy in the future. For your own good, it is better to go through the divorce formalities properly. I hope I can help you!
