Planning to go in an LTR with a plate (no worries, she initiated and I resisted for some time so held frame quite well).

How the hell do I do this setting up boundaries like a boss/without seeming needy or beta? Do I sit her down and literally go through items? Sounds a bit stupid but completely necessary. Is this showing low value?

Btw I really want to make it clear that one mistake and I’m done. I want her to know this. No joke, I’ll be out the door second that happens. How to convey this message best?

Thanks
