Here's my take. It isn't that it gets easier. In my experience it just became less important. Less the CENTER of importance, I guess.

And you know what happened? When I wasn't looking/worrying/stressing/fretting over it - is when IT happened.

Just Like Tab' said, you don't find whateverthefuck at age eighteen. Just learn from your experiences, don't ever regret trying and one day, when you least expect it, you'll find it. Also like she said, there is no perfect romantic love. It does take work, and sometimes it hurts. As long as it isn't HARMFUL or ABUSIVE to one party, the ups and downs are normal. Disagreements are life.

Patience, my young friend! :)
