If you only hear from her when she needs something, you are being used.

True. I've friendzoned lots of guys, but I've never used them. Its better to tell them you don't want a relationship then to manipulate them.

On the flipside, men who allow themselves to be manipulated and used because they're holding on to a false hope also need to wake up and realise that they're being used and move on. (I'm in no way whatsoever condoning or defending women who use men, I'm just saying, both parties need to realise the error of their ways)

Same goes for guys who manipulate girls' feelings. Some people are just jerks, regardless of gender.

She doesn't have to date him

*cough* and vice versa
