Should I be worried about my boyfriends female friend?

Anonymous
My boyfriend has a female friend. I've met her once or twice and had no problem with her until I attended a 21st with my boyfriend. I was standing right next to my boyfriend and she just started wrapping her arms around him, putting her head on his chest and holding his arm.

Further my boyfriend refuses to post on Instagram of our relationship or save snaps of me and him or even just me alone on Snapchat but she's all over his instagram and he has a album of their snaps together and screenshotted snaps of her on his phone.

They send quite a lot of whatsapps, send Instagram memes quite a bit, they are always snapchatting each other. Their moms are best friends.

I'd never get my boyfriend to stop being friends with her, I know she has a boyfriend and my boyfriend has chosen me but I have to say I'm getting worried really and wondering if this is a red flag going forward?
