Kev, it's very normal to be emotional now, like Davidswife said. You are dealing with a great stress is your life, ups and downs now are NORMAL. Just feel, no need to quantify it to be right or wrong. Feel, acknowledge your feelings, use words to tell yourself, e.g. I feel down because my mother's presence reminds me that my W is no longer around. It hurts. Once you acknowledge your feelings, it does get better.
Like I said before you are noticing your W's pursuing behaviors. See where it leads. She has not mentioned D yet, right? Kev, in my book, it's not over till it's over and then there are some who try again e.g. Elizabeth Taylor and Richard Burton. Stay the course.
