What others have said about living your own life, seeking your OWN approval, accepting that you may never please your parents and that’s o.k. – and it’s their problem if they don’t like what you do, not yours.
That said, regardless of what we do or say, there’s always a part of us that seeks the approval of our parents, or whoever is in that role. We grow up as a part of a group, and a spend our youth in a particular role. In order to really grow up we have to make our own lives and our own role in them, but there’s always that little piece inside that has other ideas.
I’ll give you an example from my own life. I grew up in a non-toxic family. Sure, we had our issues, but nobody was destructive. I am the younger of two daughters. I have married, had children of my own, have a good-paying job and can run my own show. But. Many years ago, we were gathered at my older sister’s house for a family dinner. I was helping her with the tasks related to getting dinner on the table. Some trivial decision needed to be made; I was perfectly able to make that decision, and had my sister and mother not been there, I would have. But at that moment, almost automatically, I ASKED MY SISTER WHAT TO DO. She told me, and I did what she said. Why? Just because. Had my mother been in the room, I’d have asked her.
When I eventually got into the computer field, and was quite pleased with myself at having learned to make that machine do (mostly) what I wanted it to, I recalled how when I was a small child and computers were only big fancy machines, my father was awed by a neighbor’s daughter who had learned how to “talk” to a machine.
From the other side of the fence, now, let me also say that it is very, very, very hard as a parent to NOT want to tell your children what to do, even when you know they are grown up and that it is not good to interfere. Can’t tell you how many times I have not thought well of some guy one of my grown-up daughters was seeing and had to hold my tongue (almost literally) about it. Fortunately, in each case she decided on her own that he wasn’t right for her. Then I had to simply concur that if that was her feeling then she should follow her instincts, although I sure wanted to say, “Great! He was no good for you anyway!”
If she continues to pressure you to do things you don’t want to do, or are not ready for, you must come up with a response that will tell her how you feel, or will change the subject. Then repeat the exact same response EVERY time she does this.
Her: “You really should get married. What will the family say?”
You: “What’s important is how I feel about it, not what the family says. Say, what do you think about <insert something relevant to a subject you both like>.”
Her: “But Aunt Mabel will think…”
You: “What’s important is how I feel about it, not Aunt Mabel. I read a really good book last week; you might enjoy it, it’s called…”
Lather, rinse, repeat.
