What he has said to you, without using these words, is, "I don't care enough about you for that to make me want to stay!" You thought you were more important to him and you found out your were wrong. That's like saying everything that happened the past 10 months was a lie. That hurts horribly and you did what you thought you should do to protect yourself from being hurt even more.
