What is going on with women who refuse to leave an abusive relationship? I am seriously starting to believe it is some sort of disorder. I don't mean to insult anyone or judge them. No one knows what someone else is going through unless they walk in their shoes. I am genuinely trying to understand. How can people help?

There are so many different situations in this.
Many are verbal abuse or abusive Narcissistic relationships.
Many are not abuse but circumstances surrounding children.

Nana never suffered ANY physical abuse. My ex had a clear understanding from day one that if he ever laid a hand on me the sob would have to sleep sometime.

Mine turned into a drug addict alcoholic, we had to go thro a period of treatment tries and waiting til the kids finally decided that he would never love them enough to stop.

He was a fried pie years later before he died. There is a point imo when ppl take so many drugs for so long that their mind is simply not recoverable.
His sister was the same. She died of an overdose the night my son was killed in a wreck.

Thanks for sharing that Nana. Substance abuse is another situation I could not fathom being in. I am sorry for the loss of your son. Unimaginable. Sending you hugs and prayers.

Don't get me wrong I do have empathy for ppl on drugs, but at the same time, with my ex and many other ppl thr out my life I have known I learned very quickly that if you want to help them you first have to realize a couple of FACTS & you have little affect on the results.

1. YOU can not make them stop, not thro force or love or any other means. It is a choice THEY ALONE have to make for themselves. Period. Full Stop!
2. Depending on their own constitution, you have to accept that it is a 50/50 shot of whether they will make that choice to stop & the consequences to themselves & to you if they chose not to stop.
As I mentioned if they choose not to stop they will eventually physically harm their brain &/or body to the point that survival will no longer be a choice they have control to make.
3. Either way you MUST not enable them & you MUST save yourself. You should make plans on the front end for how you or you& your children, if you have them, will survive without him or her.

i chose to save myself and my children.
