I can’t stress enough how important it is that you surround yourself with supportive people who make you feel important and special, and who enhance your life with their presence. If their presence is making you feel worse instead of better, re-evaluate why you’re letting them stay.
Be the girl his ex-girlfriend will hate, his mom will love, and the one he will never forget.
Love yourself first and everything else falls into line. Your really have to love yourself to get anything done in this world.
