Is love a course worth running?

Tweet

Over these few years of my "mature" existence I've come to realize a thing called love. No I haven't fallen in love yet, I think I'm to young to grasp the concept of being in love. However I'm quiet curious in wondering if love should actually be ran? Do we really fall in love? We are surounded by a sharp statistic of divorce rate. Everybody I see seems to be getting divorced. They can't seem to manage more then ten years together. I'm curious as to why that is? If they were really in love could they just fall out of love? If i commit to somebody i want it to be to one person only. I'm not saying those that are divorced are bad or anything or aren't happy. I'm just curious as to some logic behind it. I'm sure there are people out there older than me that could explain it a little. If we face this divorce statistic then is it really worth falling in love and getting married if its probably going to end up in seperation down the road? Is it all about chance? I'm rather curious and confused! Do we as humans actually fall in love?
