The 180 is often viewed as a tactic that might make an unremorseful WS change their mind from D to R. It cuts communication and acts of service, assuming that the WS will feel isolated, realize what they're about to lose, and 'come to their senses.'
IIRC, it was documented and named by Michele Weiner-Davis in one of her early books. She reports that a client of hers started cutting her WS off from her support, and the WS 'came back' to her. MWD cautions that it should be used as a last resort and wasn't guaranteed to result in R.
IMO, the 180 is useful for BSes with unremorseful WSes who can't bring themselves to D. IOW, it's a tool for detaching from the WS when detaching is the healthiest thing the BS can do.
It's manipulation, and IMO, if you want a good R, R has to be entered with eyes (and all other senses) wide open. If a WS needs to be manipulated into R, I just don't want to be around when the WS realizes it. Sure, some WSes might say, 'You were right, and I'm glad you manipulated me into R.' Personally, I think I'd rebel; of course, I'm not a WS.
For R to work well, both partners need to increase their authenticity and decrease manipulation. R requires honesty above all.
Also, R requires lots of communication about wants and commitments to action. The 180 limits communication. The 180 is, IMO, antithetical to R.
At the same time, it's probably a good thing if the 180 causes the BS to question what they're willing to do in the relationship. Many of the tactics aim at building up the BS's sense of self-worth and self-reliance; the tactics help the BS, and that empowers the BS. realize they don't need their WS - but that's way different from cutting communications to the minimum.
By all means, Kibo, figure out what you're willing to do in your M. If you want your WS to cook their own meals and do their own laundry, let them know and stop doing those things. If you want your WS out of your bedroom, by all means tell them and do your best to keep them out. If you want something from your WS that they're not giving you, by all means ask for what you want.
Keep communicating your wants/don't wants to see how your WS will respond. Look at the ratio of yeses to noes. Too many noes means you can't R unless you stifle yourself, and that's not R.
