you made a decision. you have to stick to it. try to keep in mind why you moved and why you didn´t move in with him in the first place. if this is his reation to not getting what he wanted, it is like blackmail.
i know you feel like everything is falling around you... but... if this guy is really worth it, he will know that he is being childish. first... not talking to you, breaking up by internet... come on! you deserve better than that and after all the time you have been together, he should know it. so, don´t try to talk to him right now, don´t apologize for something that isn´t wrong... send him a letter or message asking him to be nicer, to answer some questions you have and help you understand all this a bit beter.
hope this helps
