Chances are, she was never cool with it anyway. Oh sure, she went along with it at the time like it was an adventure, but now, she realizes (or feels) that she doesn't satisfy you. Talk to her about this, don't be a stranger on this forum, but it's her you should be talking to. She not just deserves to everything you have to say about this, she needs to know that you are going to "FIX" the relationship and be sensitive when things happen. Don't think she can't understand, you weren't the only one watching the video.
