<human>: Go back to the olden days(high school). My close niche of friends consisted of 4 major guys.

One night, I go on Facebook and I see all of them wearing the same white t-shirt and smiling. I wondered, why didn't they invite me to hang out with them? I kept talking to them like old friends but they slowly excluded me from the group.

For some reason, I still try to keep contact with them even though I know in my guts that I shouldn't because I know they might do the same thing again or maybe they always have been. idk 

I keep seeing them hang out together because they're always posting things on social media like facebook, instagram, and twitter.

Summarize the given text in a few sentences.
<bot>: I made high school friends that I kind of talk to still, but they  tend to not invite me to hang outs and it makes me really jealous, angry, and sad. Is there something I need to change about myself?
