To tell him he can't come to the wedding

[Yabadabbadowho]

I plan on telling my husband in the next couple of days that I want to separate. This won't come as a surprise but is my decision he doesn't want to separate. He is emotionally abusive and I have been agonising with this decision for a long time.
I have a family wedding in 4 weeks (my cousin) that us and 2 DCs have been invited to. I don't want him to come but AIBU to tell him he can't come this close to it?

Of course he can't come to the wedding if you split up beforehand. It would be beyond bizarre for him to go when it's your family.

I think if you are going to tell him in the next few days that you want to separate then it will be confusing for your children if you all go to a wedding and play happy families. Will your husband move out?

Of course he shouldn’t go. But make sure you tell him that, you don’t want him turning up.
