He has 3 other girls as his 'best friends' on Snapchat?

Anonymous
My (online) boyfriend showed me his snapchat list today and there were 3 girls on the list that were his 'best friends' on there (the smiling/blushing emoji). Now I snapchat him every day, and he almost never snaps me, but yet he snaps these girls pretty often apparently? I find that a bit suspicious. He got angry when I asked who they were. I don't know but I have a bad gut feeling about this. I don't trust it one bit. I know you can have a girl friend/guy friend without things being beyond just friends, but I have a bad feeling about it deep down. Suggestions?
