<human>: After several years of trying I finally managed to make a half decent friendship with a guy who's relatively new to the school (And area) which I live in, to the point where he has stated several times that I'm his best friend in the area (Due to the fact that he moved down about 6 - 8 months ago and still has ties to where he came from (Obviously)). 

Now, for a while things were going fine, but then he started going out with the other person that he really liked (The girl in question). 

This wouldn't be a problem apart from the fact that I feel like they're paying so much attention to each other that it feels like they're part of their own little group (We tend to sit with a group of about 6 people). 

It's fine when they're apart, but it's just getting so annoying. I still like the guy but I'm not sure what to do. Am I just a jealous prick? 

I'm not even sure if this requires advice but I just felt like venting.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: my best friend has been completely absorbed by his girlfriend for the past 3 months if not more, to the point that there is a permanent smell of gooseberry's when they're not apart.
