@fifteenseconds,
- you freaked out over something that wasn't her fault...after having sex with her
- you then bullied her, for something that wasn't her fault... after having sex with her
- you then got angry with her for something that wasn't her fault...after having sex with her
- you then started lecturing her for something that wasn't her fault...after having sex with her
- throughout this whole episode, there was no thought whatsoever for her (think about it).
The final part of this whole episode, mentioning her career, was pure manipulation. You didn't actually care about her career in that moment it was just something said by you to strengthen your case.
Yes, you really were that bad.

Likely you are good in many other ways - we all have our strengths and weaknesses. That said - Put yourself in her shoes (like truly). Own up to your part in this display.
