I was once going through a break up and then my dad got really mad and said "
Don't you stay with someone who doesn't know how valuable you are , if you 
Feel there is a 1% you are not his number one , show him how valuable you are
And leave him... And if he really knows how valuable you are he will come back, 
And then ... Its a teamwork of your heart ,and mind. " and it hit me real hard
