Not really an AIBU but more of a how would you deal with this.
Ex and I share ds10. We split when he was a baby. Over the years both remarried with other kids. Overall we get on well but my ex was and still is very volatile, flies off the handle, likes his own way and will kick off if he doesn't get it. His parenting style is quite different to mine, he doesn't have a lot of patience and he can be (I feel) overly harsh on ds for doing just typical kid stuff. But he's always been consistent with contact and ds does love him although I think he behaves slightly differently with him than he does with me. Almost like hes a bit worried about putting a foot wrong.
Ex is due to be taking ds abroad this summer and it's playing on my mind. He's never done this before. Along with the usual going abroad worries (covid, accidents, getting lost, swimming dangers) I am concerned how ex will actually cope with ds for that length of time (10 days) and of course I will really miss him.
I know I can't stop him going. It's not an unreasonable request for ex to want to do this. But how do I stop worrying and obsessing over it? This is one area of Co parenting that I am really struggling with :-(
