Amen!
She made her feelings known to you and it’s not that you are an adult when you get the power to decide what you do with that.
For those who are persistently annoying about imparting their familial values onto my situation I have one way I put it to them :
If you found out you had a very aggressive cancer inside of you that will kill u and you cut it out you live well for the rest of your life. No one would choose to live with a cancer that they know will kill them. My father is that cancer. Cutting him out allowed me to change my path and live happily.
It’s as simple as that.
