If you choose to listen to another person make it without conditions.
You will not feel used/taken advantage of if you make it your personal choice for your character to be this way.
Feeling taken advantage of (eg:when someone doesn’t listen back) only comes about if a person feels that they are not in control but when you yourself choose to “give without conditions” then you don’t feel this way as you are in control of your feelings/character/decisions.
I hope that made sense.
If she’s the sort of person who isn’t receptive of other people’s opinions and only “likes the sound of her own voice” then I would just remain coworkers on a pleasant basis but not become friends friends.
People who are this way anyway usually only prefer friends who are likeminded anyway don’t they?
Eg:some people who are strongly pro gay marriage don’t want to be friends with people who are against gay marriage,it’s almost like a bigotry of their own form.
So if that’s what she’s like,can you just allow her to make the decision for you?
Iow-does she really want to be friends with someone who’s values are totally different from hers?
If she wants a friend who isn’t allowed to have their own opinions…that’s a pretty distorted view on friendship imo.
