Guys advice or someone in general, Be harsh if u have too..lol I need it?

OK ive posted plenty of blogs on here some of you may have read. But what the heck is wrong in my mind that this guy who treated me wrong, i keep calling him and texing him and he keeps sayin please just move on..wtf? He had nothing to offer me, i just dont get it. And i keep texing him begging him back.. I just miss him, i cant see myself with no one but him, How can he just let go. Is it easier for men. Im just so confused because he was the abuser and did it so much cus he didnt want me out, or men to see me or anything, Then how is it so easy for him to tell me he's done, and i need to move on?
