Need help!

Hi guys. I have been with my boyfriend for almost 6 years now. It was always something about him that was different but it never bothered me.....until now. He has always played video games constantly and loves music. We formed a bond while working at USPS and I became a serial-entrepreneur afterwards. I still would work afterwards and make money. He decided to join me. He was tired of working in society. Fast forward after Covid, he never stays in a position long and makes drastic changes in life that I don't agree with. After about 4 years of dating he realized he had symptoms of ADHD.....! This guy is highly intelligent. I think that's what captivated me. He was a beacon of just at hand information and I thought it was cute.....until he started blurting out information randomly that has nothing to do with the topic of conversation, making things pretty awkward around company. Even so, I started noticing instead of being productive, he would watch the computer screen for hours listening to commentary about video games. I began to take the diagnose pretty seriously. After that, it took a toll on finances and we ultimately split. I wasn't sure if he had ADHD because he was never hyper-active. He got prescribed medication for it but I noticed it didn't make much of a difference. He then tells me he has a mix of a.d.d. and autism. What are helpful ways of understanding or coping with this type of individual. Will these type of people ever find a balance between work life and self harmony?
