The fact that he didn't eat, more then likely not the problem. He may have been sick and it just wasn't something that was noticed. What conditions was he in? size of housing? Last time you had done a water change?
If you are upset about your betta passing I'd just remain without a fish for a while. Maybe not long, but until you feel a little better. Check out what you can do differently, if in fact there was something wrong in what you were doing.
