What is it about relationships that is just so difficult?

Perhaps we're just a complicated species by nature. Perhaps we're just not that into each other or whatever, perhaps, we're all just kinda mad. Of the multitudes of relationships that I've heard of, come across and maybe even experienced, here are three main ones that I want to gripe about.

1. The traditional notion of a relationship: boy meets girl, falls in love and they get married and live happily ever after. Fairytale? Well, for some people, yes. This can happen but we all know that nothing is perfect. People work at relationships to make things good. But we are also aware of how the fairytale works out, don't we? There are the times of bliss and the times where you have to fight for the one you love and believe that you can make it. It's usually the people who don't believe in fighting who are the ones disappointed.
   
   
2. Then there is the one where the boy or sometimes girl, complicates things when there is simply nothing to complicate. While I have many examples, I will restrain myself to one. We have a man who is interested in two women, one where the woman was open to taking that step with him to pursue something new and another one where he was interested in the woman but is unsure about taking that step to take things further.The sad thing is, he is confused about who he wants and what he wants. I wonder in this case, will he ever make a decision? At the end of the day, one thing is clear. He is one confused man who has no idea what to make of things. Let me give you a tip. Nothing will happen if you don't take that first step. It's a leap of faith, ok? And yes, we get hurt sometimes, but nothing will happen if you don't try.
   
   
3. And then there is the one where the relationship simply exists online. Is this truly the evolution of the modern relationship? With so many social networks springing up online now, we've all heard of people or friends who meet online, eventually meet for real and marry or have concrete relationships but in all honesty, does this really work? How will you know whether to believe it if some guy online tells you that the loves you? Heck, he could say that to 10 other women. He could have women posting love notes on his Facebook page. Ha. Call me a cynic but I would much rather believe someone who tells me he loves me face to face over someone who only exists in an online relationship. I admit, it is sweet to have someone profess love but I don't believe you can truly know someone unless you meet them in person.
   
   Admittedly, it is much easier to meet people online than it is in person but still, technology takes away much of the essence of a person.
