Hi Charlie Candi J,
This sounds like my family when I was growing up. I'm 40 years old now. I am the middle of three daughters and am the one that is living with my dad right now since the death of my mom from breast cancer.
Your daughter will come around and "need" you as she gets older.
But to answer your question what my mom did with us three was we had responsibilities and obligations that were required to remain at home. My mom wanted us to go some days but generally she dealt with us staying at home -- it was more about her being concerned that we could take care of ourself if something happened to her and my dad (this was before her breast cancer diagnosis).
In regard to her not talking to you my mom would say I'm not prying I'm just your mom. My sister's didn't understand that my mom's "questions" of where we were going and when we would be back wasn't because she was prying but to begin the search for the body. Sad to say it that way but living in the Los Angeles Area as an adult now I can understand that comment. I think this will be the hardest part for me to let my children go and not want to protect them from the world we live in. But my mom wanted us to sprout wings and fly.
So, my mom gave us three options -- she made it very clear that it was her house and her rules we could live with that or move out, we could pay rent for "our room" but that didn't include general use of the rest of the house, or we could move out.
My parents were always supportive of the three of us and when we needed to move back home they let us but we knew what the ground rules were.
So, my suggestion think of what ground rules you want to have with your daughter and if you and she can't agree then tell her nicely that it is time for her to start her own household with her own rules. Tell her that you will always be here for her to talk. And as my mom said to me before she passed she loved each one of us but she was happy to be just a wife again. Don't be afraid to be an empty nester was what she was telling us. Her daughters were only a phone call away. Final note mother daughter relationships are the most complicated relationships on the planet but at what ever age we are we always need a supportive mom.
Hope that helps, J..
