I can relate with your sentiment. My adult daughter is one of those with the entitlement syndrome, but I must say she is slowly growing out of it. I spent my retirement investment sending her to boarding school, overseas camping trips, university visits, etc. Lot's of stuff I wished someone did for me.

My wake-up call came when I got a call at 3:00 AM one morning to buy her a new computer because she close the last one on her keys of something crazy like that. I knew I had to cut her off, because I had influenced her to become a narcissist. It did not help that her mother and I had divorced and it was a bad one. So, she could play the parents off each other. At first she cut me off for a year. Now she talks as much as she usually do.

It gets better once you put your foot down. It may not feel that way in the beginning, but it helps. My finances improved and my daughter found ways to finance her lifestyle. She may still be resentful of me in some ways, so she avoids telling me things, but she did that when I was paying as well, so nothing new. Humans tend to resent you if you help them too much. They feel emasculated and that you have too much control over them. Let her know you love her, but set expectations that she must be independent. Imagine something happens to you, and she remained dependent on you. Good luck to both of us in this parenting game.
