That was it... She was leaving now
it really hurt her that he couldnt say those three words, three little words to her after five years together and they were going nowhere in their relationship so she packed her bags and waited until he got home to say goodbye
"i'm leaving Severus, this relationship isnt going anywhere and i cant live like this anymore!"
"I cant say those three words Mione, you know i cant so go ahead and leave..."
And thats exactly what she did, leaving Severus Snape with a single tear running down his cheek... "Goodbye My Love" he whispered to the wind
