I emotionally abused my best friend.
How did you emotionally abuse your best friend?
The last few days I lied to him constantly about meeting up with him.
If you don't want to meet with your friend then tell him, but lying to him and abusing him is wrong. Constantly lying to your friend is going to breakup your relationship.
I can't help but laugh every time I think of him crying because I didn't meet him even though I asked him to meet me a few days ago.
Abusing your friends like that isn't cool. If you find that fun, you might need to seek professional help.
