Arranged to go round to a girls (who I've already shagged) flat two days before. She's seemed really excited to show me things.

The second day I tell her I'll be round at 6, an hour later than planned then no contact.

Then Today I message her one hour before I'm due and she responds, "Oh your still coming hahahaha" to which I throw out a "What?". After some pointless texting I decide to go to the gym instead and she seems to get salty and says "Well next time don't wait till 1 hour before to message me".

Did I do anything wrong here?
