<human>: Can you give me a shortened version of the text?

Sorry folks, this is a long one.

My SO of 4 years recently found out that he got into some pretty impressive schools out of country, and has since decided that he wants to attend. He would be gone for at least 5 years, since it's a PhD program. I was completely shocked by the news: we had been planning to move in together in a few months and then go to schools in the same state when I finished up my under-grad degree.

I've always been very open about my future academic/career plans. He's known since highschool that I have my heart set on a specific college & program, so he knows that I won't be relocating with him.

We have already been in an LDR for three years and we know how terrible it is. And yet he seemed totally shocked when I said that I wasn't sure if I could do more long-distance! Honestly it was pretty insulting because a) we've always talked about how hard it is and b) WE HAD FUCKING PLANS TO MOVE IN TOGETHER IN MAY. We had been visiting apartments together and had even filled out a few applications.

I feel totally blindsided by this news, particularly since he said he was only applying to those schools "for laughs." I believed him because I'm an idiot and he's always been weird like that.

He has made an executive decision about where our lives are going. I did not sign up for this. I have tried to explain to him how betrayed I feel and it seems like he gets it...hard to tell though since he has the emotional intelligence of a fork.

Am I an idiot for wanting to end an otherwise good relationship? He says he wasn't planning this but I honestly don't believe him. Why would he break these plans off so suddenly after so much planning? I feel betrayed. Can I trust him to be honest with me in the future?
<bot>: SO cancelled plans to move in together in May, told me he's leaving the country for grad-school in September but wants an LDR until he returns. Not sure I want to stay with him.
