Think about it this way.
If the person you loved was always in your face and around you, you're eventually going to get bored of him. If he does something for a while, he'll appreciate the time he has with you even more so than if he were with you every second of the day. Every relationship advice-giver I've heard of has said that the key to love is being missed, and wanting you around. However, people need space, and nobody on the planet is so, so interesting, intriguing, and entertaining that the game nerd will drop his stuff and keep all eyes on that person, 100% of the time.
I've been through this problem before. I've learned to deal, and hell, I've found my own thing to be obsessed about. It makes for a much nicer end-of-the-day hug, when people miss each other.
Unfortunately, some people think the solution is to "take a break" from the relationship. That's not giving yourself an opportunity to miss him/her, it's the signal that you're bored and aren't willing to fix the problem.
Just sayin.
