there are people who use you, stab you, they only have concerns with their problems and they only want people to think about them and their problems. they misguide you, they want you to go rebel against your parents, they want you to do drugs, bla bla bla. they share every secrets of others life that others told em in confidence but they not only share with you but also make of other peoples misery. you have no interest but they will still force you to hear how badly they are being treated by their in-laws. or how bad is their se*life is.
in short being with them makes your life miserable (if not your social life, then your personal life is the one that gets affected).
If someone "stabs me in the back" or is simply being a beep-beep I confront them directly and promptly.
This is ofcourse not the case with formal relationships. If I don't like someone at work or in college, I generally don't say anything and just be nice but not fake and overly friendly.
Peer pressure is harder to resist when you're younger, unless you have unshakable confidence in your identity.
Now that I'm older and know myself better as an individual...now that I'm more firm in my beliefs....and now that I know what I want out of my relationships and how I want to be treated....it's fairly easy for me to quit a toxic friendship.
I'm forgiving (but I don't forget). I might give you a couple of chances. But when it becomes apparent to me that your offenses are intentional (and frequent) and that you just don't care enough to be considerate....I'll decide to either ditch you (if possible) or maintain a distance from you to preserve my sanity. It's very draining to be with people who are consistently hurtful. And I have let go of people like that.
In fact, when it becomes apparent to me that even a family member (a cousin, for example) frequently displays traits that are harmful to others and can't quite be trusted.....I'll maintain a polite distance. "Friend" or family....listen to your intuition. If you often feel bad about yourself around them, better to keep some space.
i'd rather have no friends than friends like those ... i kicked my best friend of 8 or 9 years out of my life for good cuz she was seriously weighing me down with her negativity .. and i'd had enough!
i met her after a long time in the market 2 months ago in lahore ... and yes ... she was still negative ... bla bla bla ... i met her nicely, she was very persistent about having my number and me giving my number ... but i never called her, and she nither ... thank God.
