Telling Ex Husband!

[CM40]

Hi all. Hope you're all safe and well.
First time poster, long time post watcher/reader.Wanted to ask, how did you tell your ex husbands you were pregnant with a new partner???
Ex husband and I have been separated for 3.5 years! After a king marriage that should've ended long before it did. My choice but ended amicably (well as amicable as it could be) we have 2 children together. Not divorced yet- experienced a few delays due to covid, finances, he's a bit of an avoider when it comes to tough chats etc. We own a house together which I live in but have had a long standing agreement with regard to the house, mortgage, maintenance etc which works well for us both and has never been an issue.
anyway, I am in a new relationship and have been for quite some time. I am currently pregnant and am due my 12 week scan early Dec, I would like to tell my 2 children at Xmas. I'm really really stressing about telling the ex! I can't even really put my finger on why- but something is bothering my mind about telling him.
I have to say we have absolutely no friendship or relationship but work well together in partnership for our children! We are flexible and understanding where our children are concerned- that has never and would never be a problem but there is something bothering me about telling him this news!
My kids are going to be SO excited by this news! I think I just don't want anything to spoil it! This is a new situation and I don't want it to be anything other than happy.

We aren't one for chatting on the phone or meeting up away from the kids etc- we tend to communicate via text or when he collects, again it's all fine, I just don't know how to do it.

How did you tell yours? Thanks so much for any thoughts

Should've also added (sorry I didn't before) I am expecting twins! No other multiples in my family and I think this is going to make the news even more special but a little harder to tell him too.
Maybe in just being over sensitive x

You don’t NEED to tell him.
Although if you’re not divorced by the time you have the baby your husband can technically register the birth himself as you’re still married (although I think that’s doubtful that he would).
Maybe next time he comes to collect/ drop off just say “I have something to tell you” and just tell him.
I would probably tell the children just before you tell him though so he can’t spoil you telling them.
Congratulations btw.

Thanks so much for replying.
He definitely wouldn't do anything to interfere- although I fear there may be the odd "half sibling" comment which I am prepared to squash really quickly if he did.

I think you're right, I think I may just tell him when he collects/drops off the kids one day if I can do it privately or I'll call him one day and tell him.

Don't know what it's bothered me so much x
