Pulled a Houdini

When you're dating a guy or girl for a few months and one day they just stop answering your texts or calling you back, essentially disappearing off the face of the earth because they don't have the backbone to break up with you.

"Hey, how're things going with you and your man, Dylan?"
"They're not. He totally pulled a Houdini on my ass"
"Aw, that sucks man."
