<human>: My boyfriend and I are going out for a year and one month at the moment. While I'm still a student, graduating next month, he graduated university last year and working as a teacher for about year now. 

About a month ago, I got a great job opportunity in advance, but I'll have to move to another city which would put us into a long-distance relationship. When I told him about this, he was all fine with it, even supported me for it. 

However, ever since this, his texts got less and less. We usually exchange one or two texts a day, but this last month, he would only text me back one or two texts in a week. I just figured his work got busier. Then today, while I was checking ouy my friends' twitters, (I don't have one btw) I stumbled on my boyfriend's twitter account. And according to his twitter, he had a blind date on 14th,  on Valentine's day and today on 16th, he tweeted that he feels like crying because this girl hasn't sent back a text. We were supposed to meet on 12th, but it didn't happen because he ignored my text for days. He may have not been cheated on me physically, but prioritising this girl he just met before me is enough for me to end this relationship. The thing is , he's my first boyfriend, kiss and everything. I just want to disappear from his life without actually confronting him. Or should I at least give him a chance to talk his side of story? I am still in such shock I can feel my whole body shaking. If any of you can give me any advices, it would be more than appreciated.

Can you succinctly summarize the text in 1-3 sentences?
