How about I just don't invite my mom to my 25th birthday?
Why don't you want to invite her to your party?
I'm not interested in what my mom thinks of me or my life. I'm striving for independence.
It doesn't matter if you want to be independent or not, your mom should be a part of your life in such big events. It is wrong to exclude her over your selfish thoughts.
She used to be a control freak, she'll understand.
While you don't need to invite her, you really should. How would you feel if someone that you live tried to exclude you from a huge event?
