I agree with Marvin, too.
In my opinion, the"bond/connection" is broken the minute they BD us. The marriage, as it was, is gone.
Doesn't matter whether their home or not. You can't have a connection to someone who has totally shut down their feelings for you.
The MAYBE benefits I see with a stay at home MLCer are...
Most are usually Wallowers. Not many Wallowers find an OP.
They don't have the energy, even though their just as gone as the person who leaves. An OP just makes things more complicated.
So that may be a plus to reconnecting, but not always. No 3rd party interference.
The other benefit is, the MLCer can witness first hand the great mirror work the LBS is doing, IF they are. If they do the mirror work, GAL, detach and just go about their business and leave the MLCer alone..they notice.
They can see their LBS is making a good life for themselves, they appear strong, happy and independent.. and may wonder why their life looks happy and busy, when theirs is depressed and miserable.
I think that can be very attractive to a MLCer, because they don't feel strong and happy.
They do watch you.
A good example of that is Acorn.(hope you don't mind me using you are an example Acorn)
She did exactly that. She left him alone, learned to do for herself, zipped her lip, got on with her life and dropped the rope, all the while treating him politely and respectfully.
It doesn't mean it will always produce a reconnection, but it sure can't hurt and in my opinion it can really help.
Just live 'as if" their never coming out of it, start building a life without them. Some of them don't want to be left behind.
