This is going to sound harsh but your bf sounds like a grade A loser. I've met countless women that have seemingly fallen in love with similar grade of men and it's beyond logic why they so into them. One way of looking at it is he's really insecure because of his current financial standing. When a man feels he cannot provide for his woman, it affects his pride. He feels useless and therefore sees a potential threat in every other man who is financially stable and able to provide his woman with a sense of security. Another way of looking at it is he's just a 'jerk' as your friends say he is, in which case you'll be better off without him and happier in the long run.
