Take that hissing, seething image and plant it firmly in your brain for a while. THAT is who he is right now. It may be who he IS. Someone who returns a loving gesture with snarling and barking.
If he were say a snarling dog.. would you go back and try and pet it again? I dare say you wouldn't. You'd avoid contact with it and if contact was unavoidable, you'd keep it to a minimum and your guard up.
I'm sorry that happened to you. You didn't deserve to be treated that way. But.. you can use that hurt to your advantage.. to keep you strong, foucussed and moving away from this person who thinks nothing of hurting you.
*hugs*
