With a man like that, I think that breaking up over the phone would be appropriate. Just tell him that the relationship is not working for you. If he asks why, tell him the truth, that his jealousy is a dealbreaker. Don't let him reel you back in with promises to change. If he starts to yell or wants to engage in further conversation and go on and on, begging you, or whatever, interupt him and say, "I've made my decision." Then hang up.
Stop all communication with him after that for closure on both sides. I hope that he is not a crazy person who drives the 60 miles to confront you. You may want to stay at a family member or friend's house for awhile if you think your safety is at risk. Good for you
