Anyone else have a bitter parent?

So I feel totally weird about even writing this, but I just need to get it off my chest! My mother and step dad are currently in an ongoing divorce. My mother has really turned into a nasty woman in the past few years and it makes me so sad. When I told her I was engaged she told me she was busy on the phone, she sad a quick congrats and rushed me off the phone. I didnt think much of it but since then she has not shown one ounce of support. She even went as far as telling my step father (my dad passed) that I am not a kardashian and my wedding shouldnt be over 1,000 dollars and not to give me any money. I haven't asked for any, and we are financing it ourselves but my parents have money.. they have a million dollar house with a yacht. She has put down my hair color, any ideas about the wedding, told me no one would come because its two hours away, and said multiple other mean comments. I try to remind myself shes just unhappy and going through a hard time. Anyone else?
