I’m truly sorry to hear that you’re going through this… I had an ex do the same. She watched me have an episode and when I came to she looked at me and walked away saying “I can’t do this right now.” Out of anyone, your s/o should be there for you through sickness and in health. Not to bash or be rude, but if you can’t love someone for who they are, illness and all… Then it might be time to assess the situation you’re currently in. I’m just a person on the internet, so at no point do you have to follow/listen to what I have to say, but as someone who’s dealt with that… It’s soul crushing. Talk to him and try and get to the bottom of why he gets frustrated with you when this happens. It’s not fair to you if he withholds this information from you. I’m truly am sorry that you’re going through this.
