Embarrassing

So today in sociology class we were in groups and I was saying ideas and our group speaker didn’t mention any of them to the class and I told my boyfriend after class and he got angry and said I think everyone is out to get me and this is why I have no friends and some girl was walking by with her head down smiling awkwardly and then he said I need to shut the fuck up and stop being a bitch then he gently slapped me in my stomach (walking side by side he did it backhandly so it wouldn’t be noticeable I guess.) another girl was watching this time. I regret saying anything about the group discussion.
