Not since adolescence, but I have friends who fit that description. People who flaunt their wealth, their home, vacations or their spouses' accomplishments have a need to brag about their "stuff' tend to be insecure narcissists.
I knew a man who made his gorgeous, sweet wife miserable because she loved him so much yet, he continually brought up his ex-wife. The first two years were wonderful, he treated her like a Queen and then he started bragging about how intelligent, ambitious and successful his ex-wife was.
My friend became so jealous of the ex-wife that she started obsessing over it. She did everything she could to be as " perfect and financially successful" as the ex-wife. The more she tried to please him, the more she was sadistically called a failure by the man she adored.
He was a narcissist, basically was trying to recreate what he believed was the perfect woman. He was a professional but not very successful, or personable. His whole life was consumed by his need to impress others.
His first wife cheated on him and left him for another man and after five years, my friend cheated on him as well. She left him for another man--who didn't have an ex-wife. She is very happy and questions about why she allowed herself to get mixed up with a narcissist and remain in such a negative environment. Now, he is on trophy wife number three and doing the same thing to her.
