why should he get jealous? no guy should care if another guy is attracted to your girl, or flirts with her, unless that guy is a close friend. it is up to the woman to show her loyalty and commitment and to handle that situation appropriately. if she will not, then she's obviously not the girl you want to be in a relationship with. purposely trying to make your ex jealous, for your own satisfaction, is a stupid game, that only immature kids play. act like an adult.
Another possibility: he just doesn't care that much about losing you. Or, he could be messing with your head by PRETENDING he doesn't care. Impossible to tell. The real question is, why play these "make him jealous" games and cause yourself to worry needlessly? Just have a good time with him, and in time you'll know whether he's as honest as you thought.

Well either he is really trusting of you and knows in his heart and mind you wouldn't cheat or take the advances of another guy.
Also is a chance he was just playing it off, after all we can all talk but we have no clue on how we would really act until we are in the situation.
Ah he is same as me ! my ex girlfrnd also used to think like you ... she always wanted to know that why I don't feel jealous but :( I never answered her and now I can't answered her . but I can tell you :) look its all due to trust . he trust you lot thts y he don't bother about others and its a gud thing .
