I can completely understand how you feel. When my boyfriend and I were long distance, we used to talk for hours and hours over webcam. Once he got a new job, he couldn't talk as long and was so tired he just wanted to do text. I felt like we were growing apart, but he really was just busy and tired. Some people had successful LDRs where they didn't speak every day. It's really about what works best for you as a couple.
We very rarely spoke over the phone because of the cost. I had Vonage, so I could call him when he had a landline, but otherwise it was just way too costly. When he was on vacations with his family, we basically just called to say "Hi, I love you" and that was it.
Have you spoken to him about how you feel and how he may be feeling? Are you thinking he's not really just cleaning and cooking? I know that DB and I sometimes felt constrained by the need to be attached to either a phone or computer to talk (especially because it can be difficult to keep up great conversation if you speak every day and are long distance), so we needed to just cut back the amount of time we spoke each day.
It's great to talk each day, but it sounds like you and your SO might need to have a talk about how much time you each feel you need for talking each day, but also make sure you each have enough time for people/activities outside of your relationship.
