PLEASE HELP........I'm ADHD and my husband is not. He wants to leave.

Ok, so where do I start? My husband and I have been married for 15 years and have two children. He recently told me that he is "done and can't take it anymore". I asked him if he made up his mind and he said "yes". We went to see a counselor a few days later (I thought for us, but he later said it was to have someone give us direction on how to help our kids through this). The counselor spoke with us together for about an hour or so, then told me that she needed to get more history from him. I eventually "got the point" and left. Later that evening I asked him what she said and he told me that she told him that I had some social qualities of Aspbergers. I was really irritated (not that she had said Aspbergers, but at the fact that she made a harsh JUDGEMENT based on the INITIAL VISIT and I believe short history). I told him that I didn't think she was the one to help us and asked him if he would consider going to see someone else. He agreed. He says he's been in "HELL" for the last 15 years and can't do it anymore. I am broken hearted. I asked him if he could TRY and see if WE could work and he said he doesn't know how. That he has TRIED for the last 15 years. I told him that he ISN'T trying, because I was only diagnosed 2 years ago and we haven't seen anyone, used any "tools" to even try (either of us I now know). I have learned a lot about myself in the past week. He is frustrated that I don't ale responsibility for ANYTHING, I act childish, and the list goes on. I told him that a lot of his anger is from my BEHAVIOR and that with the right tools, he may realize that I AM the person he wants to grow old with. I the that he is sooooo ANGRY that he won't give it a try. We went to a new counselor who was I think amazing. My husband to us at the session yesterday that the first lady t the end of thier session asked him what was his decision. He told her he was done, and can't do it anymore. Do you know what she said? She told him that if he is done, to go get a lawyer and get custody of our kids. WHO THE HECK DOES THAT? I was like WOW!!!!! Well, the lady we saw yesterday told my husband she thinks he is "unclear" of what he wants, and asked if he would give it a little more time. He hesitated, but then agreed. I enrolled in a community college in Dec 2011 and having ADHD my homework is crazy. I am ALWAYS doing homework and I don't know what happened. Last night (with finals next week) I told my professor I needed to drop out because my family is more important  and I needed to work on this. He understood. I called my husband and told him, he didn't think it was a good idea because of the cot and I told him it was so I can work on US. After thinking more about it, I have decided (him encouraging it) to take my final and finish my class. I did tell, and that I am taking the summer semester off to focus on our family. After I told him, I asked him what he needs from me? He asked my when would it be that I will just "accept" his decision to leave and be ok with it? I told him I thought the timing should be fair (not like 2 weeks) and he said " all I can do is one day at a time, but you have to realize that I might go to the appointment Monday, walk out and be done" . I said " WHY WOULD YOU SAY THAT? You give a glimpse of hope and they yank it away". I was balling my eyes out....the kind of hurt , crushed crying. Later that evening, I called him, talked a little and then tol him I was going to bed. I told him " I LOVE YOU" and he said it sounded like he was going to,say so,etching else, but held back. So that is where I am at. I just want to know is this a positive sign or not. I want us to work not only for us, but for the sake of the kids too. Any thing would be appreciated. Oh, we made a list to take to the second counselor about what drove us crazy about the other. On my list, instead of listing that, I listed the things I HADN'T taken Responsibility for......and there were about 26 of them. I am learning more and more every day. I just hope it not too late.
