<human>: I was about 6 years old when I met this girl at sunday school at church. It was pretty much a standard playground crush, and nothing much came of it.  All of that changed after I attended my oldest brother's wedding and decided that she and I were going to get married.  This was only after someone at the wedding commented on my slick suit, and asked if I was next in line to get hitched.

Some time later, I picked a date which happened to be a saturday night about 7 o'clock. My parents drove me, with my younger sister, to the church where this all was supposed to happen. The best part is, at six years old I was completely oblivious to the fact that you were supposed to invite people, especially since my parents seemed like this would be a real thing.
I walked inside, and there was no one there. After waiting a few minutes, my bride-to-be never showed up and I broke down crying because she didn't show up to our wedding.

Can you summarize the given text in a few sentences?
<bot>: girl I had a crush on didn't show up to our wedding, that I didn't invite her to and I was heartbroken at the age of six
