I ask my ex if he want me in his life no response obviously no but he changes the subject after i said bye why didnt he say no like he has before does it mean he hate me so much to keep me hanging on?

He probably doesn't hate you. It sounds like he is a little confused about the situation and maybe wants you in his life but is not 100% sure on it just yet. Just give it time. And P.S. He must want you in his life if he still gives you the time of day to talk to him. PEACE~!
