The most twisted thing ever

After breaking up with my boyfriend he tells me he's hurt, he's hurt because he hurt me. But he never did anything about it, he didn't apologize. All he said was "I hate myself for hurting you so much" and "im hurt and torn apart" that's it. I figured he'd try to fix things in some way... But nothing... I called him after work and he asked why I'm calling and I said I don't know and he said he's busy right now and hung up.... I don't know if that means he's too hurt to talk or he just really doesn't care. Because I'm bawling my eyes out when I'm with or without him. It hurts so bad to be with him and it hurts so bad to be without him. I really just don't want him going to another girl. That's my biggest fear.... And now I'm so upset I can't eat. I'm in this daze of confusion and numbness. My thoughts are so blurred I don't know how to feel. When you love someone so much and you didn't expect them to just walk away so quickly like that you have no idea what they're feeling...
