A workaholic is a person who focuses almost solely their career. This can make it difficult for them to have a meaningful relationship and might end up costing them their marriage. For the spouses of these individuals, living through the problems can be a huge challenge. In some cases, it might lead to divorce if the problems aren't addressed in a timely manner.
One of the primary issues with a workaholic is that they aren't emotionally available to their spouse. This makes it hard to keep the marriage going because the nonworkaholic thinks they aren't important. There isn't the ability to speak about important matters related to the relationship or the home.
The lack of physical availability might also be a problem. Not only is there no time for intimacy, but there also isn't time for fostering a positive relationship. Date nights and even time to spend with the children won't happen because work is the focus.
In order to try to better the marriage, you may need to sit down with your spouse and outline what you feel is going on. This can be hard because they might opt to continue to claim they are working as much as they are so they can continue to support the house. You should insist that they find a balance between work and family. Don't continue to make concessions, such as shifting dinner time, just to accommodate the work habits that are ruining the family, but be willing to compromise so work and home can live in harmony.
Ultimately, the marriage may end in divorce. If this is the case, make sure that you are taking steps to protect yourself. This is your chance to create the life that you want, so make the most of it.
