Re: Your wife has no personality
Tried talking to her about this? If so, what was the reaction like? Does she realize that her actions are a concern for people around? If her brought-up wasn’t normal, you don’t expect the behavior to be any normal either. The good news though is that it can be fixed. First step is talk to her. She might have real hard time trusting but you can use different tactics, being really polite at one time and a bit harsh at others (but don’t start scolding, may be try emotional blackmailing) and something will definitely work which will make her discuss issues.
She does need to have a hobby. Find out the interest and may be get her enrolled in some training for that. If there are no friends, she’s bound to be socially awkward but let her groom at her own pace in front of strangers. She might be too cautious in front of family (parents, inlaws, husband, kids) to even try being social.
