Love is when you take away all the passion and fire and desire and you still find that you care a great deal for the other person. Love is deeper than physical feelings and emotions. It is how you connect mind and soul. Plus you can only meet someone as deeply as they have met themselves. If you meet half way There's a compromise. Lust on the other hand is full of passion and desire. A desire that needs fulfillment. Often times, people pursue that fire and it isn't long before the fire extinguishes and they are off chasing the smoke they sight from a far again. Love and Lust can exist together in my opinion but if you were to choose one, it is better to choose love over lost all the days of your life. Love can last you a life time but lust is short lived.
