<human>: So this is simple, my GF got a new job and works with a guy she "tried really hard to date in highschool" We've been dating over 9 months, and I'm really insecure about this. She said they didn't talk, but I can't help but be nervous. I'm always nervous about this type of thing and I don't know why. I'm her first relationship over 2 months btw. It's a big department store so they aren't interacting everyday but would probably pass by eachother every few days or so. She said "he was one of those oblivious guys that didn't know I was interested".

Am I being ridiculous?

Can you summarize the given text in a few sentences?
<bot>: Gf has new job, old guy she wanted to date in highschool (2 years ago) works there, am I being ridiculous for worrying?
