The behaviour demonstrates narcisstic tendencies. My mom's a lot like it; she brags about my accomplishments to others, has never said a word of it to me (although she'll brag about me to others in front of me...), but she passes things off as it all being a result of her being such a wonderful mother... when really... if anything, my accomplishments were more of a "must get out of here" motivation!

My relationship with my mom went downhill pretty quickly once I hit the age of having and showing my own opinions. Things are her way, or not at all... and I distanced myself as much as I could as early as I could, in an attempt to preserve myself and my sanity.
