Having been a child and a mother I can see both sides of the issue. It is hard for a mother to let go of her child regardless of her age. It is also hard for the child to let go of the need to please a parent. Both need to be done. Sometimes it is an easy transition, but all to often it is a difficult situation. Your experience is, sad to say, all too common. The good news is that BOTH of you have the opportunity to grow and become friends instead of parent and child. I had to "kick dirt in my mom's face" over my daughter's wedding. It was so very hard to do, but she learned to respect me for myself and to appreciate the fact that she raised a really neat daughter. We became good friends until she passed away. I miss her and have some great memories of the times we shared the last 29 years. Stay strong. It is for the good of both of you.
