My ex alcoholic fiance would tell me he loved me, etc, and then flip into that dark place and say he was unhappy and didn't want to be with me. He would then flip back and say I was perfect for him, that I had ruined him for anyone else ever. Later that night he would flip again...after drinking a bottle of wine or half a bottle of vodka, and behave crazily, calling me name after name. Its gut wrenching. It leaves you questioning your sanity, your emotions, your value, everything. I dunno if its some sort of game to manipulate you and hurt you like he hurts, or just that he can't decide, or that he really doesn't know, but let go of him. Just let go, love yourself enough to realize you deserve to be cherished and valued by someone who is CERTAIN they want you. Love should be a happy blissful experience, not one where you are picking the petals off a daisy saying "He loves me...he loves me not...he loves me....he loves me not."
