When you are first in love you feel it in your stomach, queazy and fluttery. You don't want to trouble it with food because its just not important. All you want is that person and to see them, be with them, hear them.The anticipation! It's a lovely feeling, but one which physiologically is based on sexual attraction. Real love then calms down into the feeling of belonging together, even when you are apart, and having a sense of mutual trust and respect. And still having fun!
