Fundamental difference between cishet men and women (+ gay men): the former typically aren't observant/emotionally intelligence enough don't ask "what's wrong" when something "looks off". The latter group ALWAYS are "see something? Say something".

You may feel it was games, but this is more a reality check that you lack emotional intelligence to question when something isn't okay with someone, that you should be checking in. It's basic empathy.

Granted the method used wasn't great because it depends on you seeing the post to be able to take action at all, but, as you said, you did.

I wouldn't normally go about it in that fashion myself, but she had the right to test, for herself, whether she's been wasting her time with someone who is not empathetic/emotionally intelligent. Nobody wants to choose someone emotionally unavailable as a life partner, because they'll never feel seen, heard, or validated. Ever.

The fact that you immediately blocked her and went no-contact, though, is more evidence that you're Avoidant Attachment and will never have relationships with real connection. If you have to rely on direct, blunt communication, instead of nonverbal, using insight and emotional intelligence /empathy, you'll never be able to connect with anyone. You're afraid of being vulnerable and are only protecting yourself by pushing away others seeking a deeper, insightful relationship.
