I know some states impose a waiting period for getting a divorce. My encouragement is that if you are in a state with a waiting period and your spouse wants out of your marriage, take that waiting period and make a full-court press to learn all you can about marriage relationships and address whatever issues within yourself or in your marriage need addressed. All of the issues may not even be fixed in a year, but if your spouse sees your effort to make changes they may rethink their choice to get a divorce.
One of the saddest situations I witnessed was a man who came to me all emotional about how he would “do anything” to save his marriage and yet probably three months into the waiting period he was dating again. I came to doubt how badly he really wanted his marriage to work.
