After many years of therapy and the death of my parents (relief regarding the rejection issues)....placing boundaries is most important for one's self-preservation.
We can tolerate, but if we make it a personal decision to do so, it's best. But, when some mouth off or try to interfere with our lives, it's easier to burn the bridge if they won't make the effort for things to be maintained civil.
The bottom line is that we hurt and have hope that others will see/recognise....but they don't because they have their own issues. We can become easy targets for whatever...once we put a foot forward and draw the line, it becomes easier.
Maybe age and experience has something to do with that process. We can't pick our families, but we can sure make decisions regarding how much we allow them into our lives.
I also need to add that once we set our boundaries, all hell can break out because their reactions can be escalated to sometimes mind-blowing proportions. If we stand our ground...eventually they may get it. Give them an inch of consideration...it's all for naught and we sacrafice ourselves once again.
