Young love and old love can be broken down into a science. It can all be blamed on circumstances and chemicals. As teenagers, hormones are raging almost non-stop. Our body changes, our personality changes, almost nothing stays the same.
I realized, being a guy, that once the hormones clear, and you can see straight again, beyond sex, beyond being horny, beyond being infatuated, that you may not even want to be in the same room as the person that you, only seconds ago, were ready to spend your life with. Without hormones blinding us, without the involvement of the primal urge to reproduce, we can see more clearly than we've ever seen before. As a guy, I know what it's like to be blinded by hormones, and then, after an old "session with myself," I sometimes wonder why I found a creature from the depths of ground zero attractive. It can all be blamed on hormones.
But where would we be if we all ignored what our lower extremities tell us? A worse world in my opinion. Of course you can't always chase whatever your vagina is telling you to pursue, but logically, the marriage rate would definitely be significantly lower than it is. There are so many marriages that began with shallow sex and continued to be something more. Not to mention how many of us wouldn't exist if our mom would have kept her legs closed. Plus, to be honest, chasing women makes life just a little more exciting.
Another aspect of relationships that is a simple science is that we all have an agenda. Whether it's sex or money, you're always more ready to stick around, and deal with a person when a person has something to offer you.
People usually get their thongs all up into a tiny uncomfortable little bunch when you talk about somebody being in a relationship just to get something from the other person. Especially if it's something like money or sex. To be truthful about this situation, it's not as bad as people make it seem. You never get into a relationship with someone unless they have something to offer. It can range from making someone jealous, to the fact that they make you smile at times when no one else can. Neither of these things is more sincere than the other. You can't blame someone for not looking for love where someone else would be. Sure, expecting a relationship to last through thick and thin if it's based on whether or not one person knows how to have sex well isn't the smartest idea. Circumstances change. People change.
Being selfish in a relationship is a MUST. I don't mean being completely selfish to the point of take take take take. (I hear thongs bunching up again.) Let's be honest, when you're in a relationship, you're in it because you think that being in this relationship will make you happy in some way or another. When your relationship makes you sad more often than it makes you happy, it's time to end it. Sometimes, simply making the person you're with happy can make you happy in turn. The urge to take care of them will kick in after a while, whether you're a life sucking leech who only takes and the idea of YOU ever giving something repulses you to the point of vomiting, or an aspiring housewife/maid.
Being with somebody should wake up your endorphins every once in a while. Endorphins are what you can call the happy chemical. they're what make you feel good, whether you get high, or married. When you take a drug, the chemicals they release don't make you feel the way you begin to feel. That's the endorphins and some other things that I don't know the name to being triggered by the drugs. Just about everything involved with being high is already in your body. Endorphins are also released when working out, when having sex, and when you know something good is happening(like you know you're about to have sex...). Sometimes just seeing somebody can release your endorphins. Because she's so pretty or so sexy.
Every relationship starts and ends with chemicals, whether it's hormones or endorphins. You just have to find someone that makes them kick in the right way.
