AIO Over These Messages Between My Girlfriend and a Guy?

I found these messages awhile ago on my girlfriend’s phone between her and a guy from her hometown.

On Thanksgiving last year she was apart from me in Puerto Rico and made an instagram post of her posing on her knees in a bikini on the beach.

We had just started dating and hadn’t discussed Instagram stuff yet so she talked to me about it before she posted. I just asked her to be respectful of our relationship regarding the post and said to go ahead and post it.

This dude messaged her out of nowhere within 2 hours of her posting when she was drunk at dinner (which she was also texting me during and told me she was) and the screenshots are above.

She maintains that it was innocent on both sides and she did not do anything wrong. I don’t really think given the context that she could have thought the guy was being innocent at best and that she was partaking in not being innocent at most.

AIO?
