Maturity is over rated :/

My boyfriend and I just had a "mature" talk about our relationship. We've been dating for a year now, and it's not as good as it used to be, but neither of us is ready to give up just yet. It's weird though because he feels like a stranger now. The old boyfriend I used to know is gone; he's a ghost. I miss him. Apparently, although we're staying exclusive, we're going to try not to be so serious. We're going to try to make it happier and back to better days... but I don't even know where to start or how to get there. We're also trying not to smother each other too much, so I haven't really talked to him much and I probably won't see him till Wednesday or something. Sigh... Why is everything a big large 3 million piece puzzle? Why can't it be like when you were little and did the ten piece ones of Winnie the Pooh or Tinkerbell?
