What are some boundaries you have in relationships?

The most obvious one is like cheating. I mean other stuff like having too many opposite sex friends, spending too much time alone with an opposite sex friend, flirting with other people, liking or commenting on other people’s pictures online, drinking too much.

What are you fine with, and what are you not fine with? What’s a reasonable boundary to you, and what’s unreasonable?

Boundaries could also mean the way they treat you, not just the way they act elsewhere.
