STBExP visiting my mum - aibu?

[Giraffey1]

Am in the process of departing from my husband. It's my decisions to split and things are currently reasonable amicable. He has just told me he has arranged to visit my mum and go for a meal. She lives an hour or so's drive away - he wants to see her before going to visit another friend of his who lives in the same neck of the woods.

AIBU or is this a bit weird? It makes me feel slightly uncomfortable but I don't know if I'm being unfair. It also feels odd to me that he will be with my mum who is meant to be on my side. That last bit sounds a bit childish, but you know what I mean - she is my mum and has told me she is supportive and understanding of the reasons behind the split.

Do other people's stbexp's go visiting their MILs?

My parents have been divorced for just over 30 years.

My dad still visits my mother's parents regularly and they chat on the phone etc. My dad's parents died recently but before that happened my mom would still visit them a few times a month.

Did he visit her alone before the breakup?

maybe he's genuine, maybe he's upto something.....either way i wouldn't worry about it.

Now that you're no longer together your mum doesn't need to censor herself for fear that it will affect your marriage.
Hopefully she will now call him out on any dickish behaviour towards her.

I see my ex's parents more than he does, but that's for the sake of our girls. They'd never see them if it was left to him.

We're also very close to DH's in laws, but I think that's somewhat different as his first wife died so there was no divorce element, plus DS1 is their grandson/nephew.
