I've had a friend of 7 years now, but I'm feeling the urge to ditch him.
Why would you want to do something like that? The 7 years of friendship mean nothing to you?
You damn right it means nothing to me
It's wrong to disappear out of someone's life without reason. You should tell your friend why you are doing it.
If they care I'm doing it, they should have asked.
They weren't obligated ask you anything to show that they care. Making them feel obligated to show care isn't fair to them. I would highly recommend you reconsider and think about this.
