Not inviting mom to baby shower? Thoughts?

My mom and I had a huge falling out when I first found out I was pregnant. She said some really unforgivable things and was harassing me over text after I told her she hurt my feelings and making fun of some of my husband and I’s wishes for when the baby comes. She sent me 46 separate messages cussing me out, and I chose not to respond to them like I would when I was growing up to protect my peace. We didn’t talk for four months and I randomly got a baby onesie in the mail from her for my birthday and a card that read “I’ll always be your mom even if you want to act like I’m not”. How she treated me in early pregnancy has really made me consider no contact. The gift made me feel some guilt about not inviting her to my baby shower next month and I’m so conflicted. I haven’t received an apology or any indication her behavior is going to change and I just don’t need that hurt and added stress being a new mom. I don’t have siblings, and dad was a dead-beat so it does pain me to not have much family but I try to tell myself I need to understand that how she treats me is not okay, no matter who she is to me. However going through pregnancy without a mothers support and love has been difficult for me as I’ve had complications and Hyperemesis gravidarum that required hospitalization. My husband has been amazing this whole time.

Do I be the bigger person and invite her to the baby shower that’s in another state, or do I protect my peace?

For reference the fight originated when it got brought up that my husband and I chose to do no kissing, but we were inviting her to come down for the birth. She cussed me out, sent me pictures of a hazmat suit, called me every name out of the son, told me any life insurance she had was going to be donated to dogs and she liked my cousins more than she ever liked me. She also told my whole family I was pregnant although I asked her to wait and sent me a picture of her brother holding his belly making fun of me.
