Advice for a 29 year old Latina…

Hi! I am feeling a bit desperate so I resorted to posting for help here. Long story short: 29 year old woman living with parents, only child, in a committed relationship, Mexican parents. Parents have always been extremely overprotective especially my mother. Lately she has been creating absurd scenarios and accusations e.g. me coming home drunk when I haven’t sipped an ounce of alcohol in months, always talking negatively about relationships trying to discourage me from dating my partner, attempting to enforce an unreasonable curfew and becomes extremely upset when I come home “late” past 9 PM. I am really trying to cope with all these issues but I have gotten to the point where I am starting to resent my mother for acting the way that she does… I am even considering moving out on my own because I can’t stand it any longer… if I were to move out I’d stop paying some of my parents bills and would reduce my support and presence drastically… any advice? Similar situations? Trying to talk to her and place boundaries does not help. I feel like a helpless child every time just like I did when I was a kid and she didn’t allow me to do things like stay over at someones house or be independent…
