Bumblebee, the fact that you seem to be amused by a conversation about coercive control is saddening.
Being conditioned to coercive control is not the same as not wanting to leave an abusive relationship.
Refusing to entertain the idea that you are being abused, doesn't mean that you don't want to find a way to end it or get out of the relationship. There really is an awful lot more to it than that.
It's wrong to make an assumption that the OP's DM does not want to leave, just because she has defended her DH by attacking the OP. Chances are that she is experiencing massive internal conflict and has very damaged thought processes, which include knowing that she is being abused and wanting it to stop, alongside not being able to see a way to end it and being terrified to admit to herself that she is in this dreadful position.
Sending a message out that some people want to stay in abusive relationships has the potential to cause harm. There will be lots of MNers who, like the OP, have friends or relatives in abusive relationships. Yes. It's crucial that those outside the abusive relationship protect themselves and their children from the abuser but it's also crucial that lifelines aren't withdrawn because people are encouraged to see an inability to leave as a 'want' or a choice.
Abusers actively work to make families and friends withdraw to protect themselves. By doing so, we do their work for them. Where someone has the resources to keep a line of communication open, can visit occasionally and keep a level of the relationship intact or can just send a message that they will always be there, no matter how long it takes or what it looks like, to help, it's far better that they do that.
It will be very easy to pick holes in what I'm saying here and twist things to fuel an argument. It would probably take a series of books to explain properly. I just think it's important the the messages that come from MN don't include that it's OK to walk away from a victim just because they are conditioned to their situation.
Please consider giving my post some thought instead of responding to it to justify your position
