Love and Lust

So I think I've truly realized the difference between the two through personal experience, although I wish I could've learned an easier way. Here is my philosophy from what I've learned.
I believe that both love and lust are very closely related. I think that to fall in lust is just as difficult as falling in love. Now, when I mean lust I don't just mean a crush. Just like when I say love I don't mean a crush either. I mean love, and there is no other word for it. Anyway, lust is just not the same as being attracted to someone. I think lust is built just like love; off the same foundation, essentially, but blossoming in a different way. From what I've learned, true lust occurs as a result of a series of patterns, just like love. I will attempt to describe love now in efforts to better be able to describe true lust.
Most love is slowly built up over time, through experiences with the person and just spending time with them. In cases where it isn't noticed at first, it will suddenly spring up and be realized. Love is very hard to break; almost impossibly hard for reasons unknown to most people.
I believe that true lust occurs in the same way. It builds up slowly over time through the same types of experiences and spending of time. The difference, however, is how it begins.

The first couple of weeks of the process is the big decider. From my experience, here is my hypothesis: If at the beginning communication is mainly nonverbal, consisting primarily of facial expression, gestures, etc., then the relationship may turn to lust. If the communication is primarily verbal and jovial, then it may be more likely to turn to love. That is just my hypothesis. Please comment on this about personal thoughts.

It's very easy to confuse true lust with love and to think you're in love when you're really in lust. Both feel extremely similar to the other, but like I said before there are still some minute differences. If you're in lust, there's more jealousy and fear, in my opinion. But if you love the person and they love you, and it's mainly platonic, then you don't necessarily worry as much if you argue; you worry about the person being hurt or sad, but you don't worry about them moving on to another person. And there is another similarity- both fears feel extremely similar. However, the same feelings of fear result from different causes.
Anyway, this topic is very confusing, but they are some of my views that I thought I would share. Please comment!
