This is not a healthy friendship. This person does not have your best interests at heart. Distance yourself. Stop hanging out, stop messaging. Give excuses if you’re not comfortable telling them that you won’t tolerate their treatment of you anymore. Do not let them guilt you into staying in each other’s lives. They might see you push them away and try everything they can to pull you back in. Don’t give in. Real friends like to see you happy and want to build your confidence up. Go to events where people have similar interests to you and you will make better friends. Good luck!
