<human>: The fuck up took place about a year ago when is was 17. I was at the park with one of my friends when i got a text from one of my ex-girlfriends who was way out of my league when we dated and is still way out of my league now and I still had feelings for her (we were forced to break up). she said that she was bored and that her parents weren't home so she was eating ice cream. When i expressed my jealousy of her situation and my love of ice cream she suggested that I should come over and eat some ice cream with her. In my nervous stupidity I said no and when she asked why is said that "i was busy". She didn't text me back for a while after that. I have regretted the decision ever since.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: A really hot ex-girlfriend of mine asked me to come over when her parents were not home to eat ice cream and i turned her down.
