<human>: Condense the text into a few key points

Backstory-- After college, I decided to take an internship fairly far away from where the rest of my friends work.  There are about 8 interns in the company, and I live with the only two male ones [22m & 25m].

Since graduation, I have basically only hung out with my roommates... the other interns have shown little interest in me. Recently, I have noticed all they (my roommates) do is talk crap about all of the other interns and how they think they are so much better than them.  This slowly started to rub me the wrong way...  However, all the other interns strive to be my roommates best friends.  When I have attempted to hang out with the other interns, I invite them over and they always seem to ditch me to go hang out with my roommates instead.  

The final straw was the other night, I went to bed before my roommates got home and was reading with the lights off when I heard them through the wall talking crap about me... since then, I haven't tried to hang out with them any more (I'm still nice/professional at work...but I mainly just hang out in my room when I'm at home now)...but I feel now they are trying to go have big get-togethers with the other interns (this never happened before) and taking pictures and posting them everywhere (I'm assuming to make sure I see them) and I feel like if they started talking crap about me, everyone would believe them just because they want to be accepted.  My one roommate is very similar to Regina George-- very attractive and charming and able to get his way with anyone.  Am I wrong to stop trying to be these people's friends?  Or should I suck it up and continue to follow the group?

I'm very hurt by what they said about me, and I feel like they are probably dramatizing it to everyone to make me look bad.
Part of me just wishes everyone knew what my roommates say about them behind their backs...Sorry, I'm just rambling now...
<bot>: Should I continue to hang out with people that are mean to each other behind their backs?  Am I in the wrong to just continue to hang out by myself and be a little lonely for the next 6 months?
