Am I the jerk for banning my mom from my house after she stole my wedding dress?

My mom has a tendency to be very reactive. She's also extremely superstitious and sentimental.

I am not. I am currently planning a wedding and we are both broke students, so our budget for the

wedding is very low. My mother-in-law asked if I wanted her wedding dress. She got married in 2019

and it lasted nine months. I'd refer to the wedding as some type of internal crisis where she

believed she had to be married by 40 and was trying to make another man jealous. She cried

the morning of the wedding and kissed her boss on the lips right in front of the groom.

She is now very bitterly divorced but living happily with her boss. My mother-in-law offered

me this dress and it's a beautiful dress. We are the same size and it is from a bridal boutique

I can never afford. I'm happy and not at all worried about her failed marriage. My mom told me she

thought it was a horrible idea and that the dress would bring bad energy. I said I'm not into that

stuff and I'm going to wear it. She called me spoiled and materialistic and cited that my mother-in-law

doesn't even like me. My mother-in-law doesn't really like anyone but her boss but I'd say she

likes me well enough and that my mother-in-law disapproves of the wedding. She thinks we are too young

but she isn't that invested. I told my mom that I get where she's coming from but I'm wearing

the dress. Well my mom came over recently and she stole the dress. I called her and confronted her

and she said that she is disappointed that I am a shallow woman and want to wear a dress from an

adulteress with a failed marriage. I told her she had two hours to return it or I was calling

the cops. She did return it intact but I said she is banned from my house forever. My mom did

apologize and she cried. She feels like since the dress is okay I'm being too harsh. She cited

that if I have kids it wouldn't be fair to keep her banned and said I should understand this is

hard for her and when your kids grow up there are always growing pains. So am I the jerk from
