No. You have every right to be pissed off.

I hate it when people make late cancellations. The same thing happened to me back in the New Year, and it gets on my wick.

If he knew it was off, and didn't even tell you, so you would've wasted your time tomorrow getting ready unbeknownst to the fact it wasn't happening. Then I think he's in the wrong.

Also, someone making other plans when they've already made plans with someone else beforehand is just rude and inconsiderate. If my girlfriend did that, I'd be livid. Especially because he didn't even tell you that it was off and went behind your back. Sounds like he'd rather hang out with his lad friends, than be with his GF.
