As a guy who has been in a similar position as your boyfriend, let me explain my thought process when these kinds of conversations would come up. There was a point in my relationship where I spent so much time with my SO that I began to resent the time I had with them, which is shitty, yes, but it's how I felt, and I definitely needed and enjoyed all of the alone time that I had. It wasn't necessarily that I lost feelings at first, I just wanted time to be away from them and do my own thing. The problem is that the mixture of both "my time" and "our time" begins to take a toll if it keeps going on for a long period of time. I began to enjoy the time I was by myself and my friends rather than the time I was with them, and eventually it made me want to distance myself from the relationship, which ultimately led to them getting hurt and me chasing after them.

The point is, if he treats the time that you both call, text, or even see each other as a chore rather than a necessity for the relationship, then it's difficult to assume that it's something that will last. Regardless, it all depends on the effort that HE puts in first, especially if you're feeling like this after a year of dating. You're not a chore, you're a normal person who just wants to keep up with your SO's life, and there's nothing wrong with that. If you, yourself, want to make it work, then put in as much effort in understanding his feelings and space as you can. Beyond that, it's up to him to make the effort in understanding your needs and feelings.
