Should i invite my mom?

So I posted about this a few weeks ago but now im 100% sure shes just not happy for me.


I got engaged end of April, my financé and I told my mother the beginning of May and she acted like she didn't hear us. We shook it off as maybe she was just surprised, or didn't know what to say. In September I showed her my wedding website and how planning is coming along. She got kind of annoyed asking me what it was for and why I'm doing it. I looked at her confused, but I understood what was happening. She just was not happy for me at all. I just asked her for a nice picture so I could post her as The Mother of The Bride. She didn't answer. Tonight we were out and ran into my aunt. She asked about my necklace that has a photo of my son, fiancé and I on it. I told her it was my Fiancé, she asked my mom why it never came up in conversation with her. I told my aunt that she ignored me when I told her too. And she acted like she didn't hear either of us. My aunt tried to get her attention but my mom continued to act like she didn't hear her. This kind of irritated me and I'm considering not inviting her. We were never close, but shes my mom. Am I wrong? Should I say something else to my mom or just invite her and if she comes she comes?
