Boyfriend brought chocolates for his bestfriends fiance, am I being insecure?

My boyfriend has been friends with his best friends since child hood, and his best friend has a fiance who he has known for around 6 years

Today she mentioned how he brang chocolates round for her because she was having a really bad dad and upset, it's rare she gets upset so I can see why he did it

We all mingle and he has no problem me meeting them etc, I'm new to being in relationships.. is this normal? Am I being insecure? I do find it sweet but also concerned
