Hi P, I know exactly how you feel. It makes me so mad that I have to give up spending Christmas Eve/morning with my children this year so the woman who helped destroy my marriage gets to spend it with my boys, who I gave birth to! Doesn't seem fair, does it? I feel like she doesn't deserve a relationship with them either. I am not so sure I can ever find a way to get past this either.
I am planning on spending Christmas Eve at my brother's house. Do you have anywhere to go? Can you go visit with your oldest son?
