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

My girlfriend of 1 year whom I love truly made a social media post today that got me upset and I feel a little uncomfortable about it. 

A little backstory, I do not talk to other girls or flirt with them or things like that. I believe that is just wrong to do in a relationship so I respect that etiquette. I would not do anything to hurt my girlfriends feelings.

So to the point, today she posted an Instagram photo of her and her guy friend and the caption said, "Happy birthday to my best friend!! I miss you so much and I owe you for re connecting me with my bestfriend. I miss seeing you everyday and walking to every class with you. You're an amazing person in every way! See you soon love you!" With all types of heart emojis. 

I told her it made me feel uncomfortable because of how she said he's amazing. she misses him, and she loves him, and how she owes him. She hasn't responded yet so I'll update later possibly. 

I wouldn't even think about doing this if I did have a girl bestriend I would just text them saying Happy Birthday and thats it. Not make it a big thing and let all of social media know. 

I feel weird because she says these things to me also. LIke how I'm her best friend and also lover. How she loves me so much etc. Then she goes and says it to her guy bestriend??? 

Am I right or wrong with feeling a little uncomfortable about this? Am I overreacting about something dumb? Reddit let me know your thoughts and advice about it.
