Adjust your boundary as you deem fit, whether or not your partner translates that as something negative is up to them. Live your life the way you want to, not under constant fear that any act could me misconstrued as some negative connotation.

If they are going to leave or cheat, they were going to leave or cheat regardless of how youve set up your boundary.

People are going to say, well if you didnt do x or have this y boundary, the likelihood of them leaving or cheating would've been less. So the likelihood is there? And youre going to walk on your toes to avoid that likelihood?

Well dont complain when you do 'everything right' and your partner still behaves in a way that violates your presumed 'consideration'. Youre going to hear others say, well they were just a bad person and youre too good for them. They will only push you to the dark---red pill side.
