18 and life to go

One of my friends recently became engaged. She's 18. I'm also 18 and the thought of getting married right now is terrifying. I've never been in love so I guess I just don't understand what kind of place she is in. The only guy I've ever wanted to spend forever with is Jesus! Don't get me wrong I do want to get married one day, but I feel like there's so much I want to do before then. Realistically I could probably do everything I wanted to while I was married; like traveling, going to school, or working and volunteering. But with marriage comes huge amounts of responsibility; like paying bills, and serious commitment. I know I'm not near ready for that, but I am happy that my friend is; and I couldn't be more excited to be her bridesmaid.
