<human>: Could you distill the essence of the text into 1-3 sentences?

Basically, we dated freshman year but we were both really awkward (and 14), and it was only for like a month (this was like february of 2014). We started talking again right around new years this year, and now we snapchat and text a lot, but I get really awkward and nervous around him whenever I see him in school, or pretty much anywhere in person. This is almost exactly what happened freshman year, and I dont want a repeat of it because I do like him, I just never know what to say. Usually im pretty socially confident, so I dont know what to do about this.
<bot>: Dated this kid freshman year, now were juniors and texting again, but I always freeze up around him in person, and dont know why/how to fix it.
