my bf is an a-hole

Im 19 and my boyfriend is 18, he still lives with his parents and is a senior in highschool, I’m a freshman in college. He is a very insensitive person and doesn’t have a filter. It causes quite a few arguements. Last night while facetiming him, he made me watch as he randomly flipped his brothers mattress with him on it, injuring him. He quickly ended the call and I didnt hear from him for about 20 minutes. We’re already long distance, and now his parents took his phone and laptop away, leaving us with no communication. I used to go to school with him, so we have mutual friends, and they agreed to let him occasionally text me through their phones, or he could log into social media during lunch at school, etc. I have not heard a word from him since he was grounded, and I have no clue how long this will last. Do you think this will make him realize he needs to start acting mature? I get he is in high school but I feel like if he doesn’t start acting mature he may hold me back.
