Why does the notion of ending up with your first and only relationship seem so ideal? perhaps it's because we love the idea of destiny and of luck, or because there's nothing more pristine than when a couple is on the same plane, sharing a common past at the same time discovering and experiencing things for the first time, like a first kiss. It's less complicated.
Growing up with a your partner makes you comfortable with each other. You don't need to try to fit in in each other's lives.
May times it's the surprise and mystery that draw people to one another--and when those elements are gone, for most people, the attraction frizzles and thus their relationships head towards the downward slope to splitsville. they ultimately find themselves starting all over in the dating scene. Dating and entering into romantic relationships are important and inevitable factors of our lives. Human kind needs partners for it to subsist. Therefore, people loves love. Love is everything to us. We love in able to trust, to love others and to share ourselves. The whole relationship thingy gives a lot of impact to our lives. That is why it's like the end of the world when we end relationship.
But how many relationship are we going to try before finding the one? For me, you don't need to find love because that is why you call it falling in love. You don't force yourself, you actually fall. People that came to our life has its own purpose, weather to teach us a lesson, to hurt us or to be with us forever. You don't set qualifications when you love, if its "the one" it will be the one. Everything will fall into their right place, at the right time and with the right person. :)
