Robert & Erin, Sorry this is so long at the front end!
From the perspective of the person with E, I can offer the following, of course it is different for everyone, so may not help at all!
Since I was in otherwise perfect health and really enjoyed running and doing things that became a bit too dangerous to continue at first, or not ever again such as snorkeling and activities in really hot weather, when E showed up in my 30s it had a big impact on my emotional well being. I felt like a weakling, was embarassed and HATED when my partner wanted to talk about it and reminded me about meds, etc (because I was struggling with acceptance and I hated thinking about it) all the things I would do if the situation were reversed! Erin, I did the exact thing that you experienced..I would apologize profusely after a siezure or aura. Once when I was being carted off in an ambulance, when I could speak again all I did was apologize to the EMTs and my partner. I was so ashamed and humiliated. It may be that the apology may not be coming from him thinking that you want one, but because he feels embarrasment and feels you deserve one if that makes sense.
Over time, he understood that I typically wanted to be alone after seiz for a while,even though that was hard on him. And that I am angry at myself and embarrassed when I forget my med or to drink water frequently, etc.. As I have slowly accepted my new reality, our communication on this has been better and I finally really realize how hard this has been on my partner. I hate that more than anything now. We have a great relationship and this is not a problem any longer, just something we have to keep in mind just as if I had diabetis or anything else you have to manage and not let define you or your relationship.
If it is possible and fits ok into your relationship one thing that you can try is to get to the point where E is not the basis of a fear that has more impact on your life than you realize, it will make it easier on your partner to do the same. I know that is selfish and not right as this is not something that you have control over. I cant stress enough to just let them take the lead whenever you can and it is safe to do so, as hard and lonley as I can only imagine that can be right now.. might work out well. It might be a bit different than before, but it will get back to great sooner rather than later hopefully! All the best for you and your loved one.
