Most Helpful Guy
Eh, this behavior sounds fairly familiar. Has he seemed distant for awhile? If so, has it steadly gotten worse? Does he just seem indifferent?
Something happened he's not tell you about. And it likely involves you somehow. After 2 weeks of no communication, he may be looking for the relationship to just die off. If that's the case, whatever was bothering him was bad enough he's emotionally detaching himself from you, if he hasn't already (FYI, a lot of guys do this when things happen they don't want to talk about). Could always try to find out, but this is a good ecample of Hope for the Best, Expect the Worst.
Your call. Good Luck.

Well firstly your reason for getting into a fight was valid. You can't be happy in a relationship where one person has to do all the work. He stopped making a effort as you said and now his actions show yet again, that he is not willing to make any effort on his side. You need send him a text telling him that you want to meet up asap to have a conversation with him in person because you want to know what's going on. Also mention that it's the right thing to do considering you've been together for a year and that you deserve to know what happened. If he doesn't reply again then you need to find closure on your own and if you struggle to do that, just take a look at the way he has treated you now as a example. Actions speak louder than words and in this scenario his actions have really shown that he's not interested in anything, not even in answering your phone call. What kinda guy does that anyway? You deserve better and you know it.
