We still continue to work in the same school. Avoid each other as much as possible. I'd like to think he can't bare to face up to what he's done. He's still playing happy families and I'd like to think I have moved on. However....
I am expected to put on an evening event for the (few) children that do a particular activity. Unfortunately, as the child is involved in the activity, the child's mother will be invited to be part of the audience.

I would have thought that she (and ex) would have the decency not to accept, but I've just received confirmation that they both wish to attend.

It's nothing to do with the child - the child is awesome. I just don't want to spend my after school time 'entertaining' his mother when she knowingly had an affair with my husband (at the time), who him no doubt will be coming along as the new step-dad. I am the 'host' of the event. God, I'm sounding so bitter.

Should I just suck it up or appeal to management to host it on my behalf?

Guess I haven't moved on as the thought is making me heave....

You need to start looking for another job. Personally, I'd go ahead with the event - show them how great you are!

I don’t know what’s wrong with people. Why is he attending? It’s not his child. That’s just sick. No decent person would do this. It’s like twisting the knife in. What’s wrong with him? Is he getting some sick satisfaction from doing this to you? Did you say at one point that you were involved in practically building this school up and he’s a LSA? Was his male pride affected by the fact that you might be more competent than him? Like another poster said just concentrate on making the event a success, but this would drive me nuts. I sympathise.

@ByQuaintAzureWasp @WakingUpToReality Thank you.

I did the event this evening. Mother and 'step-father' (ffs) were both there. I held my head high, supported my colleagues and students and it was a brilliant success. I just feel dirty. Utter dicks - both of them.

Well done! I feel for you, that must have been hard. 🤩
