How comfortable are u being open about it? One option would be for your bfs mom to gently let people know that u have a stutter beforehand, and that all they need to do is be patient and not finish sentences, keep eye contact etc. Another would be for u to easily address it if you stutter during the conversation… another would just be to ignore it and do your best to have confidence during the interactions. But I would advise not to let it get you too anxious or down or stop you from talking to anyone. Good luck
