You out greww her, she realized it, and she tried to rend your guts. Eff that. 14 years of emotional education. You got this. Your kiddo is a savage coder. Thank you for that. He inspires me. You on the other hand have more than she does and that my friend is Dignity. Don't fret, even thoigh the sun sets it will rise again. Stay strong, keep going. Maybe its time for her to learn about 'you don't know what you have until its gone'.
