Strong Doubt

What can I not live without?

With that there is no doubt,

That my fiance is my breath,

Rght up until death,

And having him with me keeps me happy,

And every now and then a little sappy.

I am told on the hour,

Which makes me sour,

That I should wait,

Which in return makes me hate,

I keep my head held high,

So that people know why,

I have him in my life,

So I can become his wife.

He is by far not an item,

I would still take him on the island,

He is the only thing I need,

To keep my happiness indeed,

So, what item could you not live without?

Mine most definitely has no doubt.
