It’s a fair point you make. My question is practicalities. She knew straight away I was being short with her. How do I explain a sudden change from cordial to aloof? I can’t say “because you’re messaging other guys”- I have no proof, just a gut feeling and she will say I’m being paranoid.
Why are you being "short" with her? Is that what you think detachment is? That's not it. Are you familiar with Sandi's rules?
