Dating a guy with Adhd. Advice and help.

I'm dating a guy who is 24 and has Adhd. Its been 3 months now. Things are good, but sometimes things can get soooooo confusing and annoying. I am very frustrated because he works so much and lives 30 minuets away from me and we hardly have time to see each other... but even though we don't see each other a lot, when we do its great. we only see each other once every two weeks cause he has so many responsibilities. He tells me how much he wishes he could spend more time with me... And we almost broke up cause of it, but he couldn't cause he said he wanted to keep being with me and didn't want to regret it if we broke it off.

I feel like if i'm not around him, i'm not on his mind sometimes...only when im in front of his face...even tho he doesn't like texting and calling he does try to occasionally remember to call and text..he has met my parents and he was so excited to meet them, which was different for me because usually guys are not ready to meet a girls parents formally like he did.

He is very sweet and affectionate when were together, hes easy to talk to and he listens VERY VERY well. When I tell him what he does wrong he apologizes and tries to change, I see how hard he tries.
Its not easy cause he doesn't open up to me too much so I dont know how much he likes me. He just told me that when he met my parents he liked me even more. He talks about the future sometimes like talking about having kids briefly or us having dinner parties in our own home, or...him saying, when we just met that he sees himself still being with me in four years. but sometimes I'm unsure.

  I have heard some really bad things about dating guys with adhd..and I was just wondering, since its only been three months, Does anyone have any advice and examples, on what you generally go through in a relationship when dating a guy with adhd, what I have to look out for in our relationship in the future.

  Also, Is it typical in a adhd guy for him to not break it off with a girl? He said usually all the girls broke it off with him....should i be worried? I really need help.
