Confused in Lust

I want you and then I don't.
I need you then I don't.
I'm so confused,
Lost in this episode of lust .
Completely lost.
This parallel life
running next to mine.
What is it's purpose?
What is it's reason?
Is there one?
You,
me
him
and her.
Complicated lives entwining,
They have no choice,
Unlike us.
I want it to stop,
I know it should stop.
I'll miss you,
your voice,
your touch,
you within me.
Holding me.
Kissing me.
Laughing with me.
Lusting me.
Im not strong enough.
I ask myself over and over
What is the point of it all?
The answer is always the same .
There is no point.
But does there have to be ?
