Insecurities

Am I just insecure or does he really do all that I suspect?

Does he lie?
Does he cheat?
I know he looks, but would he wish for us to compete?

Does he love me?
Does he use me?
I know he says he loves me, but will he leave me when he has the chance?

Does he care?
Does he really want to be here?
I understand he is here, but if he finds something better will he leave me for her?

These may all be irrational thoughts.
I should just trust the man that I love.
But how can I do that with so many insecurities.
