If a direct approach doesn't work, you can try to limit his access to opportunities to share these stories. Avoid conversations where he might bring it up. If he still manages to, quickly change the topic. You can also create a situation where it becomes clear that you are not interested in hearing or having others hear these stories. For instance, you could say in a group setting (if he shares there) that you'd rather keep your family life private and not have it be the topic of discussion at work.
You can start by simply picking one story that really stands out in your mind, like the time she volunteered at a local charity event and you were so proud of her. Then, just casually bring it up in conversation with friends or family.
One way is to make your stories really boring. For example, if you just post about the same mundane things every day without any new or interesting angle. But this might also affect other people who do enjoy your stories. Another option is to directly tell me that you don't want me to watch your stories. It's a bit blunt but it gets the message across.
Begin with a problem that your wife overcame. Say something like, 'My wife has always been a fighter. There was this time when she had to deal with a difficult boss at work. She didn't just quit or complain, instead...' and then go on to tell how she managed it. This builds intrigue as people want to know how the story unfolds.
Tell her directly that you don't like it. Simple and straightforward communication can often be very effective.
You can offer her a special treat if she sleeps in her own bed for a certain number of nights. For example, a small toy or a piece of her favorite candy.
Create a comfortable environment for her. Maybe have a cozy evening at home with some soft music and a warm drink. When she feels relaxed, she'll be more inclined to share her stories.
Tell the bully directly that it's not acceptable to use your mom's stories in a mean way. Be assertive and show that you won't tolerate it.
Facing your colleagues will be tough. Try to keep your composure at work. Don't let this personal issue spill over into your professional relationships too much. Just act normal and focus on your work tasks.
You can start by simply being there for them. Listen to their feelings and experiences without judgment. Provide a stable and loving home environment. Encourage them to seek professional counseling, and offer to go with them if they want. Also, handle all the practical matters like dealing with the police and legal procedures so that they don't have to worry about it.
She has made me more patient. For example, before I was always in a hurry, but she taught me to slow down and enjoy the little things in life.
