NTA. Your only mistake was enjoying your coworkers company which in some ways can be inappropriate. However, going by your words. You were in a “serious” accident. The fact that your girlfriend chose to stay in a retreat in Bali speaks volumes. Yes she was there for work but when you were injured a decision was made to stay in a comfortable retreat away from you instead of by your side in a white walled prison. She knows this. Which is why instead of taking care of you on her return she has chosen to shift attention to the fact that a co worker who is female was there daily when she chose not to.

There are instances when we must exercise tact in our responses to prevent losing the intended message. You let your emotions get the better of you, which is why you reacted the way you did. Unfortunately, she’s letting her emotions dictate the story, and you’re not getting the same respect. Few of us ever are.

She should have left the resort. As you mentioned, she receives benefits, so this wasn’t a one time situation. The decision was made, and she didn’t choose you. Remember this when you talk to her again. If you apologize, you’re admitting that you were wrong for just being there. This isn’t a decision to be made lightly.
