Hey BK- Glad you are having a better week. I'm curious to see what others think about you inviting H for xmas morning as I'm in a similar boat w/ my waw. I think it is fine for you to invite him as long as you won't be affected to much if he says no. If he comes, great, if not, his loss. I believe that was in 1 of the 37 rules but I could be mistaken.
And what do you mean when you say "I think my H would be happy to come over and he may think that it was nice of me to invite him since I know we are divorcing".
Are you projecting that you think he thinks you have accepted D? Invite him because you want to invite him for you and your girls, not to please him or prove anything to him, that is pursuing I believe.
