Why does this guy coworker never mention me his wife and never mentions her to me unlike to his other people?

For instance his wife is selling some fruits for like 6 $ and he was asking around almost everyone who wants to buy it excluding me I only got to find out about it through a friend that’s buying it from him and she mentioned that he asked if I would be interested in buying but never asked me why is he like that yet we talk all the time and stuff
