Her name was my password...

Now I surely have changed my password,
But my hand still moves in that fashion...
The thing is that I truly loved her,
Where she saw negative attitude in me,
It's incomprehensible for many that know me...
She ditches me for her own comfort,
'It's okay,' I say, 'Come back after your exams,'
'I'll be waiting for you.'
But what she says is, *'You will waste your time,'
'Don't wait for me.'
