How do you feel loved from the ADHD partner?

I had an emotional serious talk with my ADHD boyfriend today. I was really sick of him spending time on his own, gaming, internet, stuffs he likes. He said he needs his own time, own space. Even when I was at his place, he is still doing his stuff on computer. So I asked could we do something together next week? he said "no we spent too much time together, I need some time off myself" I was so angry because the time we spent together is me sitting on couch while he is playing computer game. So I started a big fight talking about my frustration. He apologized and he said he loves me so much and he needs me. He cannot promise me anything because he knows he might forget or fail, but he will try. He knew I have to put up with all his ADHD nonsense that no guys ever give me, but he loves me so much. He knows how important and how lucky to have me in his life helping him (his ex didn't believe in ADHD or his condition). He is able to talk to me patiently because he is on med today. But most of the time I see him is after work , because the med has worn out he could hardly give any attention to me. I know his limitation is to giving  attention but how can I feel loved while I have no attention from him?
