Confused Relationship

My relationship is one on the extremes. But its always confusing. Maybe Im the one who's confused, but yeah its kinda complicated.
From being a guy who'd never get into a serious relationship..I got into a relationship thats so serious,our families want us married. Even the seriousness confuses me. I never wanted it to be so serious. I mean I love her a lot, like truckloads, but I wanted it to be more chilled out, I never knew how it got so serious..it kinda freaks me out..all the expectations and stuff. But yeah its a very beautiful relationship. Like we're so much in love its like a fairytale. But even the fairytale story confuses me,actually. How can love be just so perfect in a world where relationships dont work and love happens everyday ? Maybe she's got this ability to make me fall in love with her every single day over and over again.Then There are times when I'll think its a waste and Im better off single and relationships suck, but thats because Its so perfect that I dont want to believe it can be this correct. Too much perfection screws things up. Thats confusing too,I know. I'll create scenes and make up fights that aren't even backed by valid reasons. Its just that it freaks me out. N then I'll think about her,and I want to be with her till my last breath.
Maybe Im just a confused soul who is lucky to have a super perfect girlfriend. And its so perfect,and so good to be true,that I start believing that maybe its untrue. Complicated. I wonder why I wrote this up,and even If I did, half of this post reads "confused.perfect.perfect.confused. lovee.perfect.confused." weird.
