Hi
@Mella ...
a few ideas, not really critical, more things to think about perhaps as alternatives :-)
Hope it helps a bit.
I went home that night
and I found one of your hairs on my shawl
(good imagery)I have to decide
if I need to be happy and if happy looks like alone
(how about WANT to be happy ?)I promised I'd stay
but disastrous days mean that I'm not so sold anymore
(I'm not sure what you are saying here ?)You said you won't pretend that you won't miss me
But you will not pretend that you can't live
But both of us deserve someone who gets it
(Perhaps lose the But on this line and start with BOTH ?) and maybe that is neither you nor me
...
You said you won't pretend that it won't break you
If I take that step and launch you to the void
But I cannot remember how it felt to know for sure
(I feel CAN'T works better for the metre at this point than cannot)I'm dreading every choice
....
You said you won't pretend it wouldn't crush you
If I opened up the door into the dark
But I can't seem to summon what was once inside me
(This time it feels like CANNOT seems to works better for the metre than Can't :-) )I don't profess to understand my heart
