So, your dream guy goes into jealous rages when someone pays you attention, gets mad if you want to be together, and ran at the first touch of boob chest?
I'm guessing that you are pretty young, so I'll do this patient like instead of just shouting at you. If you are not young, stop messing around with a guy who sounds like he is about 12, and an immature 12 at that.
Your dream guy is an idiot. A moron. A layer of of superficial masculinity wrapped around a core of nothingness. A greedy little pig who doesn't want you, but wants no one else to be with you. Get the picture?
Dump him and enjoy the other attention you are getting. You don't exactly need protecting from other guys - you can make your own choices. It is your right. And your responsibility. Not his.
Now, go have some fun.
Your dream guy is a douchebag?
There will be SO many "dream" guys along the way ... and your definition of "dream" will change as you get older.
I used to be with someone who pulled this kind of thing in his thirties.
Dump him, honey.
