 For people-pleasers, setting a boundary is especially hard because their worst fear is being disliked. That fear is often significant enough that people-pleasers would rather suffer in relationships without limits than face their fears. The short-term discomfort of setting a boundary isn't a reason to continue tolerating the longer-term discomfort of the issues that inevitably occur when you don't set a boundary. Unhealthy relationships are frustrating and damaging to our long-term well-being. Over time and with practice, setting boundaries will become easier.
