Back Stabber

One who pretends that they want to be with you but are only using you to get away from a current relationship, and then will dump you as soon as they find another sucker to take them in.

Dude, don't let that back stabber Amanda anywhere near the internet. She'll only use it to find an excuse to ditch you.
