Feeling "unloved" vs. Having "love" that is worthless

Hi, I've been lurking here for almost 3 years, but this is my first time posting. My husband was diagnosed with ADHD as a child, but his parents didn't pursue any treatment. He is now in his late 40s and was re-diagnosed in 2012. He has sporadically pursued treatment since then, but that only happens when I tell him that I just can't taking living with him and that I want a divorce. This last time, I reinforced my words with actions: I've moved into the guest room, separated our bank accounts, and informed him that I plan to file for a no-fault divorce in 18 months. He says he "loves" me and wants to work on our marriage. He is currently taking 10mg of Focalin a day (but I never see any difference between how he is when he takes meds and how he is when he does not). He been seeing a behavioral therapist once a week since the end of September to work on strategies to better manage his ADHD, but I doubt he'll ever really be able to control his more troubling behavior because he's oblivious when he's doing it and if I point it out to him, then I'm just "criticizing." I've read so many articles about how non-ADHD spouses "feel unloved" because the ADHD spouses don't pay attention to them, but I was wondering if there were others, like me, out there who don't doubt their partner's love as much as they find their partner's love feels meaningless or worthless. We've begun working with a marriage counselor recently, but I don't know if it's really worth doing if this is how I feel. Has anyone else gotten to this point and been able to get back to finding meaning and/or worth in their partner's "love"?
