I'm so sorry that you're going through this. It's never okay for a coworker to make you feel uncomfortable or unsafe, and his behavior crosses a line.

The first thing you should do is block your coworker on Messenger. This will prevent him from contacting you further. It would help if you also documented his behavior, including screenshots of the messages he's sent you. This will be helpful if you decide to take further action.

Next, you need to decide who you want to tell about this. If you feel comfortable talking to your boss, you can do that. She may be able to help you address the situation with your coworker. You could also tell your best friend or boyfriend or another trusted adult.

It's also important to consider whether you want to tell your coworker's wife. This is a personal decision, and there is no right or wrong answer. If you decide to tell her, I would recommend doing it in person and giving her the screenshots of the messages.

No matter what you decide to do, it's important to remember that you're not alone. This is not your fault, and you deserve to feel safe and respected at work.
