Relationship Question: Did Dude Mess Up or Nawwww?

A man sends another woman – who’s NOT his girlfriend, but is a business acquaintance – flowers to thank her for a professional project they just finished working on. Then, she turned around and posted the picture to Instagram, saying she loved the flowers (or something vague like that).

Literally like a complicated math problem:

1. Did dude mess up with his girlfriend by sending flowers and…
2. Is the business partner sketchy for posting pic on Instagram for all to see?
3. Does said sketchiness depend on the caption on Instagram?
