'Pulling a Belle'

'Pulling a Belle' is where one gets into a relationship for the sole purpose of not wishing to be mean. When one does not particularly like or is attracted to the other person but does not want to hurt their feelings. It is often convenient for the 'Belle' (so to speak,) although it often results in heart break for the other member of the relationship, whose feelings are genuine.

"Come on, he is a total freak...don't pull a Belle."
"I think you guys are moving a little fast, you're pulling a bit of a Belle...you should slow down and consider if you even like him."
"Is it just me, or are you totally 'Pulling a Belle' right now!?"
