Parenting
Mothers and their growing teen boys have a special issue. This is not science, not research; it is my observation and my opinion.
As a boy becomes a teen, I believe he is building a special circle. This circle is uniquely his and one in which he will invite selected women. This young man in his teens knows that his mother cannot be invited into that special circle -- it is reserved for women who have the potential to be his mate.
To exclude his mother is not easy, and it can be internally confusing. The teen may keep his mother out by appearing mean or inconsiderate to her; but, what he is really trying to do is keep her out of his circle.
The relationship between mother and growing teen son includes a sexual tension; the growing teen boy will try to overcome this by apparent rejection of the mother.
Mothers, I believe that your son is not rejecting you. It is part of his organization for his future. Once those issues are settled, you’ll likely get your son back.
