I had a guy slide into my DM's twice and whilst this isn't the first guy to or even that bad in what he said, something about this one irked me and I feel like as it's obvious from his profile that he has a long-term partner/wife that I should send a screenshot to her.
YABU - It's none of my business, don't send anything
YANBU - Send her a screenshot, she deserves to know about his behaviour
