Parental Misunderstanding

It seems that although i am a grown woman with children of my own, my parents still think they can tell me what to do, who to see, who not to see, and what I need to do to keep my life on track,

First, I pay the bills at my home. No one else helps me with the exception of en lieu of child support for the mortgage. As an adult I am capable despite your "infinite wisdom" of choosing who, when and where I go out, or not if I so choose. I am not mentally incapacitated. Just because I made bad choices in the past, doesn't mean I always will. And even if I do, it's my choice to make them. If I lose my freedom to choose, then you might as well put a gun to my head.
