Verbally Abusive Ex Still Wants To Be Friends

Ah, where to start. I got married December of last year and in July I knew the married wouldn't work out (if not before then) Quickly after becoming married he exposed his 'true self' and became verbally abusive towards me, pretty bad. I'd constantly have to walk on egg shells around him to avoid his temper. He would tell me what I 'could' and 'couldn't' say. I remember a particular fight where he spit in my face while he was screaming at me, his nose was hitting my face. I knew then it wouldn't work, but I felt like a failure and I didn't want to give up yet. So I kept trying to make it work, but it the verbal abuse got worse. No one understands how it could since he's in the military and was deployed; but with frequent e-mails he kept telling me how worthless I was among other things; it did get worse. I finally told him enough was enough and I wanted out. I know that if I would have stayed with him, he would have become physically abusive. Anyways, now he's been sending me messages claiming he 'still loves me' and is starting to 'accept' that we can't be together anymore, but states, 'can't we still be friends?' The only reason I haven't blocked him yet is because the divorce isn't final yet and I was unsure if I would need to contact him about anything. I'm at my wits end. I was doing so well, I wasn't thinking about him as much, I had quit feeling like a failure, but now I'm so depressed. I can't escape him. Do I ignore these messages or do I reply? If I should reply, what do I say? I want him to stop- before he was calling my father putting him in the middle of this; now resulting in my Father and I no longer communicating. I'm so emotionally spent I can't think. What would you do in this instance?
