I never do things for others that cross my boundaries no matter how good of a friend they are. If they are that good of a friend then they KNOW & RESPECT my boundaries. I have critical boundaries in my life that are cast in concrete & it works well & actually has earned more respect than any other way. Most of my friends were guys because I has an engineering career where it was mostly men I worked with & I had a bad marriage but refused to get emotionally involved with anyone outside my marriage & now that I'm free tho still not divorced my boundary not to ever get emotionally involved with a married man is cast in concrete..but I'm still friends..there is a line that is not even fuzzy that is never crossed....those are my values & they aren't negotiable.
