<human>: So like the title says, I'm in my 20s and I'm friendly with a teenage girl I knew from my last job. I'm in a relationship with a girl my age, and I have no desire to cheat on her or break up. I just feel like a gross person because this has never happened before and it's distressing. 

Regardless of any feelings I may have, I could not see myself doing anything inappropriate. I had a friend who, when we were 16, entered into a relationship with a 22 year and I recognized it as being inappropriate because of the age difference, emotional abuse, and power dynamic (they met at a summer job where the 22 year old was my friend's superior). It fucked with my friend and I won't do that to anyone.

I have not discussed this with anyone for fear of being labeled a pervert or something. 

The constant guilt is taking a toll on me--I'm having nightmares and anxiety.

Can you condense the text into a few key points?
<bot>: Apparent crush on a 16 year old girl. Not looking to pursue her. Am I a horrible person and what can I do about this situation?
