Help! My husband is leaving

I don't even know where to begin. My husband told me a day before our 10 month anniversary that he was going to file for divorce. He told me to leave and move back in with my parents. I'm completely devestated, crushed, and humiliated. We have been having a lot of fights recently that have not gone well but it was my understanding that a divorce was NOT something either of us wanted. I love my husband so very much and want to be reconciled with him but he keeps saying that he has nothing to give me anymore, that this is too difficult and he sees it as the only way to fix the situation. He has texted me that he still loves me and he is sorry for doing this and hopes ill be ok. This has just hurt me even more. I've been trying to plead with him not to go this route since I've have been married once before and know the lasting effects of a divorce. I keep telling him we can make it if we work at it and get help but he keeps saying no or just ignores me all together. It's been 3 days since he was supposed to file, and I've gotten only one text from him saying he does love me and he's sorry but things will never be the same and he won't ever get over the hurt of our arguments.
I'm in complete panic mode right now because divorce is NOT what I want. I'm homesick and I miss my husband, but I feel completely hopeless/helpless in this. I can't stop the divorce from happening if he files (has filed).
I am so confused and heart broken. He says there is no one else he wants, his heart has just changed about us after all the fighting and he doesnt feel we are meant to be together like he thought he did. I don't know how my husband can tell me he loves me as his wife, and wants me to be 'ok', and is sorry but is relentless in pursuing a divorce instead of working it out! And he just ignores me every time I try to talk to him. What in the world can I do??

I've asked him to do counciling but he refuses. Things really blew up in my face today with the situation. I went to talk with my husband earlier this morning before he went to work. He informed me that the papers had been filled. He was very distant with me for the first half of the conversation and full of anger. Come to find out my parents pretty much verbally attacked him on Sunday when this all happened (not to my knowledge at all but i had suspected something happened). My dad stormed over to our home and demanded all my stuff back and started chewing him out. My husband had called my parents to make sure I was ok and my mom attacked him over the phone. (I think I may have heard a bit of that conversation, but I was really out of it at the time)
Now, my husband already struggles with his faith in God, and my parents are super religious. He had been telling me recently how mad he was at God for allowing all this pain and strife in our marriage and had been slowly falling away. Well Sunday night pretty much closed the book on him with dealing with Christians after how my parents treated him. He said he ended up loosing all the respect he had for them that night. He said the guilt was starting to set in on him for the divorce but he also went out Sunday after the fight with my parents and found Pot to smoke he said that he was really upset with himself for doing that as well.
I was very surprised how open he was with me this morning since our communication had been so awful all these months. He talked about how he didn't think he was himself anymore, that after everything that had happened he told God to just stay away from him for awhile. He said he still didn't think that this was ever going to work with us, especially with how my parents and him are now, but that he did still love me and he again is just too tapped out to fight for it anymore. He said that he had 56 days to decide whether to go through with the divorce or not and that he had purposely not filed a piece of paper with the rest, saying that if that certain paper isn't with the rest of the paperwork at the end of the 60 days the divorce won't go through. He called it his 'fail safe'.
He has changed a lot since I saw him (only 4 days ago!). There is a hardness/edge to him that I saw him fighting with during our talk. Eventually he started to loosen up and we even joked slightly at times. By the end he was hugging me and saying he would promise to always be there for me. It was then that I had to harden up a bit and I just told him, if the divorce goes through, as much as I appreciate the thought, I wouldn't be able to handle having him in my life, knowing that ill always want more. I said instead of making a new promise he needs to keep the ones he made to me in our marriage vows.
I'm still so very confused as to what is going on. He said that if we do decide to work this out I've got to be out of my parents house (which is so true) and I need to go get a place of my own. He did say he will be thinking on if he can handle trying again because in reality he doesn't want to go this route, but he didn't want me to get my hopes up. We left on good terms, but still so many unknowns and not really any peace. There is SO much prayer that's needed for this. I'm just at a loss and feel so out of control with this. I admit, I'm struggling with my relationship with God in all this too. I'm trying to keep my head on straight but its getting harder and harder as each day goes by.
