Hi. In the Flinstones, Wilma mother never liked Fred, there is tons of exemple like that. Sometime they don't like how they look or their friends or their jobs etc... Mothers (and fathers) often want to live their live trough their kids so they have a second chance of being more happy than they are or finally get to live a hidden dream.
Often (and specially in the case of a Mother), establishing a familly with kids eventually calm things. There is perhaps the opposite at play, she might want to have you for herself as some fear getting old alone and she might want you to stay single for that purpose.
