My best lines on commitment say...

Love...
...is a special life we share...
The joy of happy moments,
the warmth of favourite memories,
its being with you,
doing the everyday things...
... together...
and though sometimes...
they may not seem ot be so exiting,
there's a comfortable feeling...
...that sharing 'em brings.

That's what love is to me.
Sharing a life...
... that together we've made so special...
