i think u have done all you can , u have been decent in offering him a chance for a chat
he probaly feels rejected , hurt and embarrased , lie low for a while and in time he and you will proably be friends again , you often find this with men , i went out with a good friend of mine of 14 years , realtionship lasted 6 months!!! now he cant talk to me and it is horrible , but you did the right thing if you was not happy i imagine its akward at the moment but these things pass good luck xx
