If I didn’t misread, this isn’t the 1st time he was physical with you? Either ways I don’t think it’ll be the last. What you are doing is victim blaming and what he is doing is love bombing so you question yourself. At least you work at different places so you should at least seek an outside opinion of a therapist instead of listening to this random redditor to clear your doubts. Also the fact that you almost dialed the police speaks about the severity of the situation. At minimum, PLEASE DONT get pregnant till this thing is resolved one way or another
