<human>: Some context: I'm visiting one of my best friends for the weekend and went out with him and his girlfriend last night. At one point I wanted to take a picture of something trivial at the bar, and having recently decided to download Instagram, decided to Instagram it. My friend's girlfriend is in the shot, interacting with what I was taking a photo of. It is in no way seductive, but it's also not an unflattering photo of her.

As soon as I post it, I get a series of (increasingly not passive) aggressive texts from my girlfriend about how fucking weird it is. Apparently multiple friends of hers asked her who the girl was.

I can understand that she's embarrassed, and I can understand how, without context from the rest of the night, posting a photo of some random girl is weird.  That being said, it's a cool photo and I don't really think I did anything wrong. Deleting the photo would be an admission of guilt and I don't think it would repair the damage that has already been done.

At this point all my friends are telling me I've done nothing wrong, but I'm a little concerned they're just being supportive and telling me what I want to hear. 

So I'm asking you, sane reddit denizens, was it a grievous social media faux pas? Or is it just an unfortunate situation given the circumstances (namely, I don't have a portfolio of photos of her and I together on Instagram yet). Was I insensitive or is she being overly sensitive, or both?

Condense the text into a few key points
<bot>: help learn me social media by telling me if I fucked up by having my first (and so far, only) Instagram photo include my best friend's girlfriend in it.
