Of course we can be shocked / surprised and sad/ or angry for our other parent ..... but we often do not have all the information.
It is hard IMO to really see parents are people .... in a relationship outside of being parents.... Most parents act better around kids like nothing is wrong. Many feel their relationship is not connected but who we are effects every relationship in our world. when we are happy or unhappy kids know.
Some fight openly or are truly unhappy yet think it is best for the kids.... There is no one size or answer ........but some may find that maybe they are better parents/ role model for kids...... when they are happy as people. i think we can see things differently depending on our age and experience. Grown kids can see with hindsight parents may have been better off apart.... MOST kids choose a side and can have a difficult relationship with the other parent.
What would you like to do with this information?
Was your reaction to confront him or tell your mom? there are probably many scenarios in your head.... what do you fear will happen? they break up and how that effects your world ... what happens next?
