so this guy

So I've been seeing a guy lately. He's not one I was very interested in, but as time goes on; I'm really starting to like him a lot. I met him at my job about 2 years ago. We tried talking at that time, but he knew I wasn't quite over my ex yet. So now that I'm readily available to be with someone, he's wanting to try again. Besides all that, every time he gets on the phone while he's in my presence, he's considering to be his future girlfriend. I have no problem with that cuz I can see a mending future with this man. Only problem is he is so busy with his job. He told me since day one that he's a very busy guy & sometimes he'll forget to text back or call. I like this guy a lot & would love to spend more time with him. My question is, how do you deal with a busy partner? cuz I hate to feel neglected or feel like I'm bugging him.
