So part of me thinks it is very intriguing that OW is uncomfortable. Because she should be!! I keep waiting for you to post that she is gone because she has certainly hung on with all her claws.
Maybe that is why X did the kiss and the family pics thing. Did you feel as if he was trying to get to you? If not, maybe he was trying to make OW feel better.
But if it is hurting you, you might want to think about this some. Maybe you are not all that detached. Maybe you need to be careful about what is going on here so you do not get hurt. Step back.
And just out of curiosity, as you chat, what does OW do? Do you speak to her?
