Running 2 Get In Shape

So now I have a serious marriage problem. It all came to a head about a month ago. I was being overly jealous and my wife said she thinks she wants a divorce and just didn’t know how to say it. We talked that night and I stayed out of work the next day to try and fix it. She said then she thhouushe needed some space, but in my hurt, my incredibly worst pain I have ever felt I tried to control and fix it. I went from not being intimate to constantly being as loving as I could. It seemed to be getting better to the point of having sex twice a day, but even then some times she couldn’t reciprocate. She saw a counselor last night and they decided that she needed to take some time for her Susan’s for us to work on each other before we can work on our marriage. I am now sleeping in the basement with no real physical contact except for hugs in morning and evening. We have 2 kids and stay strong around them but when the go to bed I go downstairs to give her space. She says she still loves me,but can’t garuntee that we can get back. I have been selfish not listening to her and treating her right for a lot of the past eight years. I haven’t eaten hardly anything and can barely exist right now, but I know to get her back I have to be strong and show her I am ok. Life really sucks right now, and I am scared to lose her. I don’t know what to do any advice is appreciated.
