Agree. I believe there are more people than one thinks that are like this. I can understand this. That's why couples should have addressed this situation before marriage.
After a certain age, children do NOT need you standing over them catering to their every need. They need to get out there. They need to experience some failures in life, and in the long term gain self confidence. This mother sounds like she was an overbearing mother would thought she missed out on some good things that made her happy in order to cater to her children.
That’s her own mistake. You can have children and still enjoy life.
