AIBU to think this was insensitive from my partner

[Emmpp]

I know I'm being a sour cow but aibu that my partner is so over excited about a birth of a new nephew exactly on a day when it's 5 months since I miscarried our baby?
He doesn't seem to realise what date it is and how his excitement might be affecting me.

I know people have babies and life goes on and I don't grieve anymore, but every month I remember what we lost...

I'm sorry for your loss.

But YABU. I would be more understanding if the nephew was born on what-would-have-been your due date, or exactly 12 months after you miscarried. But I'm not sure what makes the 5 months so significant. Would it be alright for him to be excited if the nephew was born day later/earlier?
It is possible to grieve for your own loss and still be happy about something else.

You are not a sour cow, you're grieving for your lost baby. However, you need to let your partner know how you are feeling if you want his support. He might not want to bring the miscarriage up for fear of upsetting you.
I think there are some good support threads on this site if you're struggling.
