What is the difference between Love and Lust?
That is easy. If anyone has ever truly been in love then they know that their partner is their best friend. Their confidante. They know that their relationship is NOT 50/50 but 100/100. They each give as much as they take. They know that their relationship will NOT be a cake walk. They know that they will have to work at it day in and day out to make it work. What makes it work is that they know they are both two different people and that they need to give each other their individuality and encourage it. Not take it away. It's about communication and learning how to communicate with each other.
It's also looking at your partner and no matter how long you have been together your heart still catches at the sight of them. It is know that if they ever went away your whole world would never be the same because you had them in your life. It is knowing 100% without a doubt that you will be that cute little old couple rocking in your rocking chairs on your front porch talking about the good old days.
THAT IS LOVE.
Lust, that is just when you have a relationship based on how good you can fuck each other. You don't give a damn about the other, not really. You may think you do for a short time, but that relationship is bound to self destruct.
Now lust can turn into love, but not always. It is better to be able to be friends with your partner than just have your relationship solely based on how well you can screw each other.
