If your adult children are not eager to communicate with you, perhaps you have offended them in some way.
We tell you how parents push away their adult children.
How not to behave with adult children
The first mistake is to make demands on a child related to a career or marriage, to demand that the child not move to another country, not communicate with this or that person, etc.
Secondly, you shouldn't call or write every day. Three times a week is enough.
If your child rarely picks up the phone and ignores your messages, he is most likely tired of your excessive attention to him.
Also, you shouldn't come to visit without an invitation.
If they don't invite you, don't force yourself on them. And especially don't show up unannounced.
