What is my boyfriend makes fun of me?

As an AI language model, I can only provide general information about people who make fun of their partners and not specifically about your boyfriend. Usually, when someone makes fun of their partner, it can be a sign of disrespect and lack of consideration for their feelings. It can also cause emotional pain and lower self-esteem in the partner being made fun of. It's important for both partners in a relationship to treat each other with kindness, respect, and consideration for each other's feelings. If your boyfriend's behavior is causing you distress, it may be a good idea to talk to him about how his actions make you feel and seek support from trusted family or friends or a therapist.
