How can some people be so mean

You put all your trust and heart into a man, he treats you with kindness and sweet words. For just a moment you feel safe in his arms, are caught up by his charms. You feel like a team and he speaks of a life to be lived together.

And then one day, its like a switch turns on and he becomes another person. His words no longer sweet, you barely recognise him as the one you let into your life, in faith, in trust.  He seems not to care how you feel, if he is making you cry, if he is kicking you when your down. 

You wonder, did this man change, or was this the real him, waiting to pop out at some destructive moment?

Its hurts.
