The only love advice I'll ever give

Love is a very odd thing. Yes, you've probably heard this a million times before... However, it is still a concept which I, (still a teenager,) am still exploring. During the last few days, I've come to realize this more and more as I've witnessed such blatant examples demonstrating it this week. Since my love life consists of little to no substance: it has been only through others that I've witnessed such interesting events.
Yesterday, I watched as a friend of mine was scolded by his girlfriend after his beverage was knocked over, it's contents poured onto the floor around a booklet of his. Why do I mention this? Because it was not he, but she who knocked it over in the first place. They argued, she stormed off, then came back two seconds later and apologized... Am I the only one who finds this odd?
You'd think that these two wouldn't really be poster children for a long healthy relationship... But you'd be wrong. They've gone past their first year anniversary without showing any signs of slowing down, arguments and all. Obviously, love is not predictable, and it seems that its unpredictability is part of what makes it so appealing. When routine is applied to every aspect of modern life: It is only natural that we have at least one means of refuge.
Though unpredictability may be an aspect of love, it isn't necessarily a good one. Unwanted pregnancy is mostly what I am referring to, but there are other things that can go wrong. Still, I have to say that even in an unfortunate situation like unplanned pregnancy, there can be a silver lining. I have a friend who has just recently become a father. His son, Cedric, was born with the umbilical cord wrapped around his neck. He couldn't breath on his own for a couple of hours. In such a terrifying situation, a silver lining is very difficult to find. But, Cedric recovered quickly, and is now out and about at 7 lbs after a week of life. To see how happy his father was the day I met Cedric, and to hold Cedric in my arms, was to me evidence of his father's conviction; as well as Cedric's bright future. Unpredictability has its many ups, as well as many downs.
The only thing that I can say for love is that, while logic is not a factor, it can be and frequently is a beautiful sight. Again, being inexperienced with being in a relationship means that my impression is based mostly on those around me. You may totally disagree with me about all of this, and that's ok. For those of you who don't, I'm glad I can help. The only advice that I can give: The person that's there for you at the end of a long day is probably your best bet, and don't let limitations get in your way. Everyone faces road blocks, and the couples that make it in the long run do so by driving through those obstacles, arguments and all.

Thanks,
