Have nc for this as very outing.
ExDP and I split 7 years ago when DC were 2 and 6. He moved countries a couple of years later and has only seen DC a handful of times since, calls them fairly infrequently, doesn't support them financially at all. He and I really have nothing to talk about and don't communicate any more unless vital.
Yesterday, he rang DC and had a very banal conversation with them for about 5 minutes then suddenly put on this weird fake excited voice and said 'Hey guys, guess what? You have a new stepbrother! And a new stepmother!' Then after a minute or so more of chat, he just ended the call.
The whole thing was completely bizarre and the kids were a mixture of disinterested and wtf. I sort of downplayed it and luckily we had friends over for lunch so DC were distracted, but am I wrong in thinking that this was a crappy way for him to tell them?
