This is my opinion only and I am no way an expert as I now have a zero relationship with my daughter but a great one with my son.
I told the kids everything the day after BD. I now wish I hadn't but I was in shock.
Once I got a little on my feet I tried not to have any influence on their opinions. I confess I didn't do a great job as it became common for me to have attacks, disappear for days and I was often on the phone with friends talking about the situation. I'm sure they heard more than they should have... I can't take any of that back and I feel it's a factor, not completely but a factor for me losing my daughter.
Now I'm 100% encouraging of my son to have a good relationship with his father. The girl can't replace me, for my son AND daughter, again I feel she is a nonfactor. Could I have made it a big deal and ask son not to go to the wedding?of course, and if asked he would have stayed home. What would have that accomplished?
No im glad my son talks to his dad. I wouldn't want it any other way.
That way I can carry zero guilt for my family's destruction. My daughter and the Leaver abandoned me, not the other way around. ... and I carry no responsibility for any animosity between family members that I can influence.
Karma is about me and no one else. I only wish the best for their relationships and hope that will come back to me in the future.
