I do agree that it's good to write down what you believe it is reasonable to expect. Because so many times I knew that in theory x, y or z wasn't good enough but then some man would come along and I wouldn't feel ....entitled
to walk away because of the 'issue' that I knew in my heart was not good enough for me.
I did this a few times until I don't know, something snapped in me maybe I just finally genuinely understood and believed that I could not only BE happier alone but that I was more likely to be happy alone. Since then I've found it easier to give up and walk away from men.
You have to FEEL the rules, not as rules, but just feel it so entrenched at your core ''i want this man's focused attention'', and ''If he's dating other people as well as me then eugh''. You have to be brave enough to not care if you put your terms out there and he walks away though.
I've had that. I put my terms down once (just, no circular dating if you want to date me) and he shrugged and walked away but I felt very empowered actually, not rejected.
I can see why the rules get slated though. It depends what you want. But the core principal is don't accept shit that you don't want just cos you're a people pleasing lonely singleton.
I recommend reading a few books about self-esteem as that probably has a more naturally similar effect to the rules. eg the six pillars. listening to a lot of clips on youtube helped me too.
