I think there is a difference.
Not wanting to lose someone because you love them, care for them and want to grow old with them at your side is a good feeling to have. Working on your relationship because you feel this way is right. Not backing down in the event of misfortunes is also right and not “desperate”. We cant justify leaving our husbands when they lose their jobs, fall sick or some sort of calamity (nauzubillah) comes into your marriage.
However, making this person the sole means of your happiness to the point where you depend on them for everything is wrong. That is a problem. Having the courage to walk away when you’re being mistreated is something every woman should have but so many dont…and their situations are all different. Its not fair to call them spineless or whatever because they’ve been through a process that renders them helpless in their own situation. It takes a lot to walk away in such scanarios.
