Well, there is plenty of journalism on the subject online, digging into who she was, their first marriage etc, Albert himself is quoted as stating that his wife was better at math than he was. Well, I read a little of this and then factor in that Mileva Marić,1875-1948, and this epoch of history and its treatment of women in science. Early 1900's and women in science, and this woman is surpassing her husband in the math department. I dont think we can properly asses what kind of beautiful mind this woman must have had.
Edit: Ill just add that Einstein is still one of my heroes, its just an acknowledgment that we’re all a product of our time.
