She failed to mention that her ex is a woman

I’ve been seeing this woman for a couple of months now. She’s never hidden the fact that she was married and she would talk about her ex from time to time, but it was only recently that I found out her ex is a woman. Her ex has a gender-neutral name. I’m not bothered that her ex was a woman, I'm more bothered that she never mentioned that detail to me. Love her or list her?
