Why does it take years for some women to leave the wrong partner?

I’ve been reading a lot stories on here and witness in real life, people can’t break the toxic patterns leads to them stay with the wrong person for years or still stuck now, then regret the time they’re wasting and afraid to start again, especially in today’s dating climate.

For complacency or fear of being alone, kids financial stability? In hindsight, do you think that you’ve known the end from early stage? What makes you to make the final decision?
