Am I overthinking for nothing?

I am completely fine that my boyfriend has female friends and talks/hangs out with them, but after some months of being in a relationship I noticed there is some girl he talks with everyday on Snapchat whom he has never mentioned before. He said she is just a friend and no one special, but I noticed he especially updates her about what he does and she is on his top list. he admitted she is someone he wants to get to know better, and I think it’s a little bit suspicious he hasn’t mentioned her before If she really is just a friend. Am I overthinking?
