Progress?

I'd like to say my life is finally getting back on track again. I just got a job at Spirit Halloween (the coolest place ever) and even though its only for like 2 months, it's something to get me on the right track. Along with finally getting a job, I should hopefully start classes at Northwestern on Wednesday, depending on which classes I sign up for on Monday. Me and Sean will be celebrating our 6 month in about a week and I couldn't be happier with him. I love him with all my heart, but is it normal for me to doubt our relationship a little bit? I can't help missing the sense of adventure that comes with a new crush, not knowing how things will go, the challenge of trying to get them, and I don't have that with Sean anymore. Everything is so easy, so natural with us, that the adventure is gone. Is that normal?
