My husband has fallen out of love - learning about my ADHD issues

I am new to this site, but I have been reading through a lot of the posts and have been finding it very helpful - knowing i am not suffering alone.  My husband of 12 years has recently told me that he is no longer in love with me.  He wishes to remain in our home - separate rooms - to allow his regular access to our children and support me in getting healthy.  He does not wish to work on our marriage, as he says those feelings are no longer there for him.  I have been researching ADD/ADHD, as I was diagnosed approximately 5 years ago (focus for school).  I was not aware how greatly ADHD would impact my social life.  My husband is more aware of how the ADHD has effected our relationship - but is still not available to work on the marriage.  I have started seeing a Psychiatrist who specializes in Adult ADHD - in hopes of getting the appropriate assistance I need, as well as proper medication for my symptoms.  I am so angry that I was so unaware of how ADHD would effect my social life.  I am so frustrated that my husband does not feel for me the way he used to - he is stuck in the negativity I have brought into our lives.  I know with assistance I can become a healthier person, I need that.  Right now I am so very sad about loosing the man that I love, a man that I would not have intentionally hurt.  While I process my daily lists in my head, and proceed with these lists I have greatly neglected the man I love.  Through this neglect I have created a loss that I am not able to recover.  I understand why he is making the choice, but I do not like it, I want to show him that we are good together - I don't know....
