Advice please-Women empowerment Needed:)

So the guy im dating.... We had plans last minute and made plans in the morning of one day. I told him anytime and sometime after 11pm is ok for me depending on how work goes and he confirmed that would be fine for him too. He told me he would just most likely be relaxing in his house all day... However,

Later on, that night it was 9ish and I texted him Im done. By 10ish PM, almost 11pm, he texted me back saying he was at the movies with his friend.

Now ... ok is it only me or is this ok? Am I being too nice or is this rude of him to do? The other side of me thinks this could be a bit rude but seriously I need advice like is this rude or is it ok if Im mostly fine with it?

Would you be fine with this if this happened to you? What would you have done?
