What is love? HAHA (Random Ramblings)

I often find myself asking this question these days. Like somehow, one way or another it feels like I'm lost. Do I really love him? Is it not just me saying 'I love you' out of habit or just for the sake of it? Did I fall out of love because of the distance? Am I just thinking too much because I've got nothing to do these days? Or it is not that I don't miss or love him anymore it just that I got used to being alone these past few months? What exactly is love? Is it feeling the butterfly in your stomach? Feeling giddy and jittery whenever he's around? Or is it the feeling of safety and comfort? Isn't it weird for me to doubt my feelings like this? I wonder why...
