Don't doubt your own judgment. Throwing things is violence. It tends to escalate and not decrease. You are in potential danger. Get away and don't go back; do it carefully because violent people get worse when rejected. I'd recommend that you leave without him finding out (if you confide in anyone he will find out) and go to a safe place. Tell your dad and he will help keep you safe. Love is not enough to keep two people together long term. This kind of problem does not go away. Therapy doesn't help because these guys are great at manipulating the therapist. Just go. You will get over him. Some partings are sad, but necessary. Take care of yourself.
And let us know how you are doing. I am sure many others on here will also feel concern.
