How can she have happy husband-wife relations?

-hi there...My sister is married from last 3yrs.she is educated and had good life before marriage as usual.after marriage her life is good in initial yrs.but after 1.5yrs his husband went abroad for some work and then their life path has been ruined(married life).They both got changed.Now she doesnot want to stay with him..After coming from abroad his husband has been changed like a hell.Her inlaws also got changed and being some much mentally stressful for her.She wants to run away and want to make her career for something but she cannot..Does she plan anything for her bright future by carrying the marriage.Please help..Your sister thinks that her husband changed, and he in laws changed but the truth is that she didn't know them well at. After she got married she got to know her husband and now she doesn't like him. If she had taken a longer time to choose her husband a lot better she wouldn't be crying out.



Just imagine that if she wants to kick the one responsible for her unhappiness she wouldn't be able to sit down for a whole month.how can she have happy husband-wife relations?

How does anyone ever ! I know why not go out and find someone who can take up some of your time !
Where was she living?

Where is she now? Divorce is legal in 95% of all countries. She needs to get out.
