New to forum- just need to air it out

I am with my husband 8 years, married 2, and he "claims" to have adhd, but was never formally diagnosed...we already see a therapist, although most recently ive been asked not to bring certain things up so im not sure even what we are accomplishing...my husband has a hx of drug abuse and has been taking adderall for many many years...but not as prescribed... He'll fill his 30 day supply and it will be gone in 4 days...for a while i started taking his script and not allow him to fill it... But now he's of course manipulated me to feel like he's entitled to it... Telling me that without it he has no sex drive, doesnt want to be with me physically... Tells me he's the best i'll ever have so i should be thankful for the adderall, etc. Granted, in other respects he's great with cleaning, cooking, etc, but he even just recently quit his job and if it wasnt for me sending out his resume, he'd have no prospects...and even callbacks he takes days to answer sometimes...but meanwhile says he'd never be without a job...

 

he also recently does not get along with my parents which puts a very stressful strain on me... My dad is not a super easy person by any means to get along with, but even after a huge blowout with my dad and putting him in his spot, my husband still goes on late night rants and raves picking apart even the most simple of statements that seem very benign to me, but that he constantly finds as somehow insulting to him... He is short tempered, barely sleeps and when he does its restless... He either is always tired and depressed, cant be bothered, or awake hypersexual and i cant keep up... Ive even been told when i initiate sex it doesnt count if he wasnt in the mood... In other words when hes high and hypersexual, thats the only sex he wants... And its like 2 hrs of me pleasuring him to the point of exhaustion, watching endless porn clips, etc. Its not fun anymore...i even caught him parousing craigslist ads to fulfill his sexual fantasies when i couldnt keep up...

in one breath he loves me, i make him a better person, cant imagine life without me, how lucky he is....and in the next breath im this terrible person who doesnt fulfill him sexually, cant stand my parents, am unattractive and no one wil have me besides him, that he could have whoever he wants, breaking stuff around the house during his raving, etc...

im really starting to see and feel like this wasnt the man i fell in love with... I do feel like i am falling out of love with him if i really havent already... I question everyday if it would be easier alone...we dont have kids...as much as i hated being single, being married to someone who doesnt make you happy is not so great either...i do still care for him, but at what point is enough enough...
