Unless you think that your X conned your S to fake that he crashed and hurt himself, then I suspect your S DID fall and hurt himself. So were probably dealing at least with a real event.
Kids can be fairly predictable. When a child hurts themself, they generally go to the first person they get the most nurturing from. Many times, that's the mother. In my case, it tended to be me because my W was a basket case when the kids got hurt.
Then couple that to a kid wanting to feel safe, so often they want BOTH parent's support, it is possible that he both wanted you for nurturing and ALSO wanted you because you were the absent parent. Kids often call for an absent parent when in trauma.
Finally, a couple things could have been going on with your X. Either he didn't know how to deal with it... or your S was making so much fuss, your H just didn't WANT to deal with it... COULD NOT deal with it...
You say your X has dealt with this type of thing in the past. Do you mean, since the two of you have been D? Or when the two of you were still M and you were still available for the kids, even though X took initial care?
So was your H checking up on you? Maybe it was an opportunity for him to at least know where you are. Just as likely, he was putting that on you because he felt you needed to take responsibility.
Don't forget that your H still lives in HIS OWN REALITY, that YOU left the M. So he likely feels that you've dumped these types of responsibilities on him.
When you wonder why he is calling during these times... whether he's "checking up on you"...
what is your thought?
That his curious about your where abouts and maybe asking for help?
Or that he is prying into your business where his nose doesn't belong?
