Breaks up all the time - does he have adhd

I have been together with this man, he's 41, and ex alcoholic. He has 3 kids with his ex wife he was together with many years. I'm unsure if he is adhd, and i'm trying to understand what is happening. He had broken up with me 7 times in the 6-7 months we have been together. When i first met him , he Said that he thought he had adhd and he had it as child, But was never diagnosed with it. After a while i could see Signs that he had adhd and said i thought he was right. Then he wouldn't talk about it anymore and just said he didn't have it and we shouldn't talk about it anymore. He is impulsive, wants to do this and that, want to go on a cruise and other things, and suddenly not. He have a lot of things he does, planning all the time, is very energetic and just the way he talks about things stresses me. Just seems like the smallest things stresses him. Suddenly he can be so annoyed at very small things and throw things through the air(not at me)

He is totally in love with me for a couple of weeks , want to live with me, wants to get old with me and just talking about future , and i can really feel his love. But all of the sudden he just pulls away, become cold and distant , and when i ask him, he Says that he has to many things on his mind, he just can focus on his children and himself and can't have a girlfriend. Then the day after or a couple days after he just acts normal and is coming back to me again. He has done this 6-7 times and did it last week again. The days after he just acts normal like nothing happend. The same as he did the other times. Wanted to be friends and stuff, just like the other times. Eventhough he is an ex alcoholic(he's on Disulfiram) been sober for 1 year, but feel in alcohol for 4 months ago, he still talks about drugs, weed, all the time and eats all of my strong painkillers. Everytime i talk to him about things ( makes him responsible) he makes all kind of excuses and can't take responsibility and just pulling away. 

I just wanted to hear if this sounds like a man with adhd. I really need to understand his behavoir.
