Dealing with parents and love life

I would love to get opinions from ladies in my situation.
I'm an adult and I can make my own decisions however when my high school sweetheart and I decided to get married this may, my mother put up a fit. My mom and I have NEVER been close. I am definitely a daddy's girl, and I'm from a split family so I lived with him. But now that I am deciding to get married and start my family officially she all of the sudden wants back in my life. I'm lost in why the sudden interest in my life and was wondering how people handled similar situations
Thanks
