Feels Like Husband is Giving Extreme Mixed Messages about Divorce

After a nasty fight a few weeks ago, my husband packed his things while I was at work and moved out. The following day, he leased a new car, signed up on a roommate website and printed the paperwork off to file for a divorce. I was blocked from his phone and had no way to reach him regarding bills or responsibilities, let alone to ask where he was or what he was planning to do. The only way I was able to reach him was by reaching out to his or my family.
[A little backstory: without getting into details it has been a very rough year and we have BOTH admittedly disrespected and been not very nice to each other in the course of it all. To clarify, however, I have absolutely zero proof of infidelity, and I have looked for it.]
About a week after leaving, my husband came to the house and told me with no emotion that he wanted to proceed with divorce. Initially I admit I thought the only way to "resolve things" was to divorce but after some alone time I realized a divorce won t resolve anything, and I do love my husband. Naturally I pleaded he reconsider, but he left to go back to his friends house.
A week later, he came home and spent the night. The following morning he told me he would be going back to his friends for the remainder of the workweek and coming home on Friday, which he did. We talked the following Saturday after he was home and the conversation ended with me telling him I hear and respect what he is saying, but to please consider the magnitude of the decision to divorce, and he said he would.
At this time, my husband has been back for a little over a week and maintains he wants a divorce. I have realized I have some anger issues (not physical aggression, but I have a quick tongue and a quick temper) issues and have begun anger management, but he firmly and coldly said that my anger had ruined our marriage. He claims there is too much pain in our marriage and that while he can forgive, he can't forget. I told him that I didn't feel I had ever been the wife he deserved in our marriage, and that I would be a better wife to him while we are sharing a house if nothing else.
Recently he began saying he wants to be just be alone. He doesn't want to compromise with anyone or have to ask for someone else's take on a big decision before making one. He wants independence. (Leaving me wondering is it really my anger or not?). He wants to be able to do what he wants when he wants, but he says it is not about "playing the field" or sleeping around without commitment, he just doesn't want to be married anymore.
The confusing part is that since he's been home we've been getting along great. He's been doing things I had previously asked him to do for years, such as texting when he's leaving work so I can start dinner, or being more mindful of how much time he plays video games. We actually played a video game together this weekend and laughed together. We have been having sex again. There have been no arguments, (I've noticed we are both trying harder not to let little things become big things), and I'm actually finding myself enjoying his company again. He will talk about things like fixing up the house or future plans that include me, but then he will casually discuss how things will be split later on. It's like he's making an effort for the first time in years and enjoying the improvement, but why would you do it now, of all times? Someone please help me make sense of this.
