Advice ?? :(

Ok So I'm 16 & My Boyfriend Is 18 & Today I Was Getting Ready To Get In The Shower Gathering All My Stuff So As I Walk Back Into My Room My Boyfriend Starts (Jokingly) Pushing Me Telling Me To Leave The Room *we joke with eachother all the time* so I was kinda getting frustrated cause I told him to stop I just wanted to take a shower so I shoved him back (not hard) & he gets serious & pushes me into the closet mirror & throws my towel at me & pushes me again to where I almost land on my baby & Idk what I should do honestly ☹️ how should I feel ? What should I say ?
