First on the table.

....I have a boyfriend at the moment. To help keep identities secret at the moment we'll call him "Mr. Carl". I've been dating him for about three weeks now. Everything is steady, we don't fight, we get along extremely well, and my friends like him a lot. Everything is going so smoothly.
I left for about a week to go home and found more fondness. I thought I felt something for him, but contemplated the reason....

Why do we fall in love so fast? 

I've fallen in love in the past and have gotten hurt from it. We all have had this happen to us once in our lifetime. We know it's a bad choice to jump right into it, but yet we still do it.
Do we really wish to have someone to care for us or for us to care for? I grew up in an environment where I had to care for animals. I fell in love with them like any child would for their dog, cat, or even goldfish. Unfortunately they were cattle, which meant in the end they would be sold to market. I would fall in love with these animals for the two years they lived, then watched them be sold. Every year I would endure this. I told myself I would always be careful with love after that. Yet here I am wondering if I love this man, yet so early.
Perhaps we want to be loved so quickly because we're afraid of being alone. Grant it most of us have good families, but it is not quite the same love you can share with another man or woman or an individual away from your original roots. Perhaps we could be scared of being left alone or having no one to call us when they miss us, to hold someone when we're scared, or to kiss someone goodnight before you go to bed every night.
It may just be human nature.
The romans and greeks were marrying by the time they were 13 or 14. They had full lives before most ever reached the age of 20. The Tudors in England were engaged to someone before they were even 10. They would know who they would marry for almost years before it ever even happened. Now and days people won't get married or commit to each other until they're past their late fifties.
My opinion is that we are scared of being alone. Being alone in the dark is frightening, not having to share memories with, not having someone or something to hold on when things get rough. We all hate to go through some things by ourselves. When we think we're close we aim for love.
13 years old, 15, 18, 25, 30, 45 or even higher to some....we all want some form of love. So when we see the chance we'll jump for it.

The only questions I know that are complete and full are math questions. These questions that I'm willing to ask and perhaps answer on my own won't have one answer. They'll be questions that need to be asked and should be discussed. In today's society we forget a lot of simple shit.
Let's just talk about it. What bothers us and what makes us happy, without being forced by someone who thinks they know.
So let the questions begin and conversation and opinion....

Not at all intimidating, right?
