Hmm, quite possible that he doesn't want you to flirt with others while he could do what he pleased. Plus, he was probably doing to the other girl what he was doing with you... I personally find all this kissing and cuddling of random people to be hilarious, I mean, if someone random does it, it is possible that they might do it to others too. Anyway, my advice would be to see him strictly as a friend (and that means, no physical stuffs), and since you have just broken up with someone else, just think about whether you want to go through more heartache when you are vulnerable.
