Did I do the right thing by deleting his number?

I really like this guy but he's been very flaky. He cancels on me all the time, yet he asks me out again and again. Last night, he texted me to cancel again, so I decided to delete his number. I always text him first usually, so now, if he really wants to talk to me, he'll be the one who has to do it first. Did I do the right thing, or did I overreact?
