Being harassed by a graduate supervisor was a very serious problem that needed to be solved with positive measures. Here are some suggestions that might be useful: 1. Face the problem with your girlfriend. If your girlfriend can stand up bravely, then you have a greater chance of solving this problem. You need to provide her with support and encouragement, and tell her that you understand her difficulties. 2. Talk to the instructor. If the instructor's behavior is obvious harassment, then action needs to be taken. You can talk to your mentor alone and explain your thoughts and feelings. If the tutor refuses to apologize or change his behavior, he can consider seeking help from the school or the relevant departments. 3. Protect yourself. You need to ensure your own safety before you talk to your mentor. You can seek help from friends or family or consider reporting harassment to the school or the police. 4. Learn how to deal with it. If you feel unsure about how to deal with harassment, you can seek professional help. You can consult a psychologist or counselor or consider taking relevant courses or training. Being harassed by a graduate supervisor was a very serious problem that needed to be solved with positive measures. You need to face problems with your girlfriend and talk to your mentor to protect yourself. You also need to learn coping skills to better deal with similar situations in the future.
