"She got mad and told me this was about her not me."
That is an admission on her part, that she considers herself separate from you, which compared to a loving relationship, the two become one. So in her subconscious mind she does not consider the pair of you as a single unit - rather there's only "him" and "her", and no notion of you both being together.
Sounds selfish, which doesn't work - my view is that a loving relationship should be a giving contest.
