I'm going to ghost my friend after lying to me.
What do you mean you're going to ghost them?
I'm going to stop replying his texts right here and now.
I am sure that it's frustrating having your friend lie to you, but you shouldn't cut someone out of your life for that reason. At the very least, talk to him first and explain why you're upset so he knows why you're ending the relationship. Otherwise, he will be hurt and confused.
Nah, I think I'll just ghost him. I don't feel like talking to him.
Don't you think you should give him a chance to explain himself? You might have just misunderstood the situation and might ruin your relationship for no reason. If they're your friend they deserve a chance to give their side of the story.
