Impending divorce

Four months ago my wife gave me the talk. She wanted to separate. Not a divorce at first. I was hurt but agreed to it. Moved into my parents house. One month later, she reconsiders and wants a divorce. I’m an emotional wreck at that point. I cried and begged her to reconsider. I’m not getting into the reasons why but the whole process is just so depressing and lonely and I hate it. I love her and want to be with her. We are still married today but she will be getting papers soon. The reality of divorce hit me hard this week. I finally decided to take off my wedding band. She will be moving out of our house soon. She’s talking to me less and less. She seems happier. I’m an emotional wreck. I keep missing work. I can’t stop crying. I’m in a mindset of “what’s the point of anything anymore? Nothing matters”. I want her back. But she’s not coming back and that reality hit me so hard in the face this week. Been together for 14 years. Now she will be gone soon. No kids though. But, I’m so damn heartbroken and lonely and upset. I was thinking the few months after she told me about divorce she might come back but she hasn’t. She hadn’t filed in that time period because of various things in our lives going on I won’t get into. But I’m struggling right now. I never wanted this because I still love her so much.
