Dont take it personally....but!

Don Miguel Ruiz, says in his book The Four Agreements: “Nothing others do is because of you. What others say and do is a projection of their own reality, their own dream. When you are immune to the opinions and actions of others, you won’t be the victim of needless suffering,”
Sometimes this advice is much easier to follow than at other times - especially when we feel that trust is involved.
We may feel that we have trusted others with our secrets or feelings or love and they have disrespected that gift.
But I would have to aggree that the only one that fully understands your reality is you and to think that others will see things your way 100% of the time is really an unrealistic assumption.
It is hard not to be yourself and each person's emotional investment in any given moment and situation is different so what may hurt you totally may mean absolutely nothing to someone else - we should not be shocked by this because it is what it is and often to understand it as "nothing personal " will save you a lot of grief.
