How's your D going? I have the same issue with my S11, he is an only child and we literally spent all of our free time with him since his birth. I told him about the EA as part of the Exposure very early on, he teared up that day but has been strong since. Luckily my WW was rational about this and we worked out 50/50 on custody very early on. She volunteered to take him to his baseball practice on my days as they have early starts (4pm sometimes) but I'll pick him up from there. Of course everything is still theoretical for me as my WW is still living in the house. Move out date is imminent though as separation agreement has been signed.
