Because you love someone, you may make allowances for unacceptable behavior for a while, or even for a long time.
But this becomes a value conflict within yourself. On one side, you love a person and want to stay connected, on the other side, they do something that offends you at a deep level.
Over time, the dissonance of this conflict can become more difficult for you, so realize that your decision about how to handle the situation now might not be the same decision you make a year from now. Stay alert to your inner pain and inner messages about this, and don’t be afraid to change how you respond.
Also, despite your inner conflict, don’t be afraid to stay the path you have chosen if you believe that this is right for you.
At every point in time, let your values run your life. Make your own choices about such situations, and don’t apologize for them.
