I need guy help for 20 + please...? ?

well hes 20 and im 24.. we've been together 2 months. and i thnk hes comfortable with me already.. i go down and visit him every weekend.. and during the week he doest call or text me anymore. only on sunday ( the day i go down to see him) and wed-saturday i dont hear a word from him. ( his mom calls to say hi and see how i am) i talked to him about it, and he said hes "weird" & "not a phone person" which i somewhat understand, i dont like the phone either. but a text takes like 2 seconds. i know hes 20 and has adhd and rarely ever finishes things hes starts..., but he used to call me everyday and text me too. and all the sudden its like he wont. my friends say its just his age, and hes showing me who he really is. and he doesnt have to impress me anymore. but i want to know what you guys think... im trying to accept it. but i came out of a really bad relationship a while back, and my patience left with my ex, and im trying to be patient with my new bf. but i feel like im over thinking and making problmes out of nothing. and i dont want to mess this up. i really care about him, and he cares about me. how do i just let this **** go and not bother me so damn much?
