Update: divorce is now more than half a year ago. Today I learned accidentally that XW is planning to marry OM this month. I did a decent job DBing during the past three years ever since OM entered the picture. But today I couldn't help myself and wrote a mail to XW asking her not to invite our kids. Too bad I am on a remote business trip for several weeks and can't talk to my kids in person before the event. But I wrote to them about it and that they should decide honestly for themselves if they wanted to attend and that I would accept either decision.
