Why pursue relationships?

 
I'm posting this simply to see different personal perspectives NOT religious observance...

 
Last night I was thinking, as I usually do, and started to wonder about the actual purpose of romantic relationships- Obviously you are interstice in them, probably physically attracted to them and want to get to know them... What is the core meaning or basis of Love?

 
As youth, we are still maturing and whether we want to admit it or not, we don't know everything now that we will in several years and we haven't gained crucial experiences yet. You don't know if you ever will because the future is impossible to predict. But why continue it, if for example, it would be extremely hard for it to work the following year or even you don't know what you want out of it. Is there then a point to try to continue? Anything can be accomplished through love (or so I'm told) but what if you don't feel that unending, 100% sure of it love?

 
There’s a lie that we all search for our whole life. It’s a lie called love. Love is a lie because of all the emotions it takes you through. For love makes you cry/laugh, love makes you sad/happy. Love sends you on such a rollercoaster ride love make you lose your mind. Now, anything that sends you through all that can’t true can it? Love is a lie or is the truth I am just too afraid to love.

 
Time and time again I have gone down this thought process… and then I get stumped. I have no perfect answer, I have no solution at all, I don't know what to do or what to say, the only thing I know is that I have a lot of thoughts floating around and now I'm curious to hear the everyone else's..
