Nearly Ruined Wedding

Backstory: My mom and I have never been close. She was always an angry person who would hold grudges. Ex, When I was about 10 she didn’t talk to me for 5 months because she got mad at me. I always said when i turned 18 I was cutting her and the rest of my family off


Fast forward: My now husband is too nice(sometimes a bad thing) and always said to just forgive and forget. So I did to some extent. I invited my mom to hair and makeup, the wedding, and included her in everything. Morning of the wedding everything was super chill and nice. We all went to an expensive hair and makeup salon. My mom started tagging me on facebook in things saying like “2pm wedding start..3pm ceremony..etc.” and i said hey can you just not tag me in those posts because I’m having issues with people hacking into my stuff and i’m afraid if people know when i’m not home they’ll try to rob us in our area. And that was it. 20 mins later I see her sobbing in the salon corner. Causing a huge scene. (she always needs attention) . Salon staff are trying to calm her and she won’t stop . I asked her what was wrong and she yelled in the whole salon: you’re a *****. because i asked her not to post that on facebook. She continued to sob for the duration of the salon appointment ruining everyone’s time there.
Am I too harsh in saying enough is enough and finally cutting her out of my life completely ?
