If he truly loves you, you'll know.
he loves you,
Try leaving, just say, sorry this isn't working for me and watch the response, if he's in floods of tears then you will know!
Well you try putting him through the wringer, spend his patience out. Make him like fight tooth n nail for seven months or so, deny him all. access To you while he gets to read how much you state you care for him and see if he is still there.. if he is /read he loves you more than you do him, and he needs to get his head checked.
Tell him you've killed someone.
