ADHD in adults and dealing with it?

Many people would not make difference in our live but thinking he is rude however it is simply the way adhd thing and don't process information, like this is example.  When i ask him why he doesn't respond to my question and his answer is because he is doing smth else as " watchin videos" very simple thing to answer. So i ask another question 5 min later, as he is texting friend, he responds with "yesss, probably. " which is not relevant to my question. I am like are you even listening?" He answers "yess just let me do my thing. " Third question in a roll he is not responding i amnlike feeeling ignored and his telling me he can't do both things at the same time. This is only one example conversation of ours that shows ADHD when he is angry he shuts down and want to be left alone then in my way of trying to help him because i love him to death he pushes me away telling rude things and doesn't let me to talk and help then i think i did something bad and makes me sad because i think smth is wrong wanting to fix the things i never took adhd thig seriusly untill recently that causes all those stuff but no matter what i love him to dead and would do anything for him.  l just want to see how other people with adhd are dealing with relationships and being open with them. Thank you very very much. 😩❤️❤️❤️🙏🙏
