Why can't I forget him?

I made the choice to stay with my partner ,
for the kids sake this is how its got to be.
So why can't I just forget him ? .
for it seems he's forgot all about me.
He's all I think about all through the day ,
every minute that goes by it's him I miss.
I miss his smile and the way he used to look at me ,
the smell of his aftershave and his kiss.
I wonder what it is he's doing ,
and if he thinks about me and misses me too.
I'd give anything to see his face right now ,
make sure he's well and happy is all I want to do.
I never meant to fall in love ,
tried so hard to keep my feelings hid.
Oh why can't I just forget him ? ,
bury my feelings deep within and close the lid.
I'm struggling everyday to remember to smile ,
and pretend I'm over him and my feelings are all gone.
There are times i wish I could end my life ,
but it's my kids that are my reason to carry on.
