Beginnings

I’ve been talking to someone for a some time now and we both want something but we’re scared to get hurt. We really like each other. He’s some time away and we’re busy. I have severe anxiety so I try to get things as straightforward as possible. Do I tell him that his inattention and seeming ignorance is frustrating? Or do I just wait it out? My anxiety has convinced me that he’s losing interest when he says he isn’t. I hate that this is causing me so much unnecessary stress. Any advice?
