When one spend most of the time with this particular person, it might automatically become one's habit. And the moment this person is not by one's side, eventually one will feel rather awkward. Thus, thinking of that particular person on all times. This often causes some sort a confusion, and so one will be wondering about one's feelings. Not many know how to differentiate from habit to love. As they most likely think that they are in love or have some special feelings on one. However, if one able to analyse all the unusualness, things will be much easier.
