Cheating??

[fredv3b]

If a person doesn't feel pressured to act this way or that by rules decreed within the relationship, they are less likely, it seems, to overstep boundaries, aren't they?

If a person doesn't feel under pressure to obey the rules, then they are more likely to obey them??????

That doesn't really make sense to me.

Someone who doesn't like the rules is more likely to 'feel pressured' into obeying them, but he breaks them because he doesn't like them.
