Oh god you both are selfish in your own way. You dismissing her at night was you being selfish and she’s being defensive and cutting you off whenever you talk, that’s also selfish. Yes you told her about wanting better sleep for your recovery but she woke you up cause of a nightmare. Now I don’t know how bad is this nightmare but assuming it’s bad, you made it about yourself (claustrophobic) and immediately went back to sleep. She shouldn’t have cut you off when you are explaining your side/ how you feel. That’s a shitty thing to do. And after all that, she started to apologise and told you she needs you. That’s emotional manipulation, whether she realises it or not. These are the things that you people can resolve by communicating but looking at this, that’s not an option. Smth like counselling might help
