Don’t finish his sentence for him. If you are introducing him to new people, have an action plan. Ask him if he would like you to introduce him or if he’d like to introduce himself. A lot of us (probably all of us actually) have an issue saying our own name. He might appreciate you taking that burden off him by introducing him so he doesn’t have to say his name. To be honest, this is a question you should NOT be POSTING on Reddit and SHOULD be POSING to your boyfriend.
