It's hard losing people you think are your "friends," but that just proves that they really aren't a real friend, and you don't need to keep them in your life, especially if they are taking you towards something you know isn't what's best for you.
It's true. I've known this in so many relationships. But also, you have to be patient. Because what if the other person doesn't want to talk? If they truly love you, they will come back to you. No matter how hurt they are, or how much you've been hurt.
I live my life by this I completely cut people out if they hurt me enough. Some people judge me harshly because they think that I'm to harsh. But the truth is I cut this people out because I find that this is the only way to continue with my life.
