My relationship is fading..

Me and my boyfriend. We're happy together, we're fading tho. We love each other a lot and fading isn't good here. So both of us have been busy for the past few days and he can't exactly take a call or text me back since he's busy with family stuff. And I respect that, I think it's cool that he's always caring about his family. But what should we do? We talked about it a few hours ago and we don't know what to do. I come over or he comes over at least once a week. So we see each other every week. We respect each other and when one of us is a little mad, the other always understand and will give the correct response or action.

If you and your boyfriend/girlfriend are fading a little bit, what would you do? Please help, he's the most important person in my life and I can't be without him.
