Marriage is a daily challenge to try to make things work. When one spouse suffers from a mental illness like bipolar disorder, the the marital struggle is more intense. There are some instances in which a spouse's mental illness can contribute to or cause a divorce. Unfortunately, this can be just as complex as the relationship.
For the person who has been diagnosed with a mental illness, the divorce can thrust them into an unwelcome period of change. This can lead to more complicated feelings that are difficult for them to work through. Making extra appointments for mental health counseling might be beneficial in these cases. In others, the downward spiral is going to continue if it is left unchecked.
The confusion and depression that often accompany divorce might make it difficult for a bipolar patient to hold it together long enough to work through the terms of the divorce. This can put the process in jeopardy by slowing it down considerably.
The other spouse might resent the difficulties that the bipolar person is having. This can filter into every aspect of the end of the marriage, but it won't help the situation. Instead, the spouse must remember that any progress is worth the effort.
For couples who have children together, the difficulties will likely continue throughout the child custody arrangements. It might be beneficial to try to work with the bipolar party to ensure that they are getting the help they need so that they can continue to be a central factor in the child's life.
While there is a chance that the individual's mental health status won't affect the divorce, it's highly likely that it will need to be addressed at some point. Speaking to your attorney about the circumstances of your situation can help you to determine a course of action.
