You know him best. To figure out what the motivation behind his behavior is (think of another time when you had expressed a wish of similar nature and what his response had been)
It is quite possible that his male ego had gotten bruised and now he is giving you the silent treatment. Either way, take it as a blessing in disguise because he hurt you already and you do not need any more of that. Continue to take care of yourself and don't even wonder why he is doing this (because you wondering about it is not too healthy- you're still thinking about him after all) Show him that you're stronger or even more stubborn than him and cut the contact off for good. He had his change with you and missed it.
