Boundaries are not directly used for you to get your WW back. At all! And they are NEVER ever to be used as any type of punishment.
Boundaries and ENFORCEMENT of boundaries is for your personal safety and peace of mind. You enforce your rules and it makes you stronger. Oh, it will PISS her off! She will HATE you. You will be the worst person in the world. She will say hateful things. Call you an ass. Blah blah. You're not an ass, you are only taking control away from her and the wayward hates losing control of you!
You see, waywards want to control you. They want the benefits of having you there at their disposal. Do her bidding, slave. And be grateful she gives you the crumbs off her napkin while she sleeps with OM.
SHE DOES NOT RESPECT YOU.
When you are stronger with boundary enforcement and no longer a pushover, she can do nothing but respect your boundaries, which results in respecting you by proxy. That alone is not enough to bring her back, but it is a good start for getting your balls back.
