Knowing you love someone isn't always ENOUGH or knowing they love you. You have to be happy inside and out, and the way it sounds he is hurting you more than making you happy. He is putting you through an emotional roller coaster. And he will probably continue as long as you allow it. I know it is HARD to walk away. but I guess it just comes to the point where you almost have to ya know?
Wishing you the best...
