Angry at husbands reaction

I don't really want to sound sexist but this does sound like a male reaction by your husband because he is unable to "fix" this for you. It doesn't mean he doesn't care about your feelings.
Like Dickens says, he might also feel guilty.

I was going to suggest what Dickens just said.
Congratulations on the new baby. 🎊

Sorry about typos grrrr

What a sad situation.

Congrats on being a (step) Grandma xx

Of course you’re going mourn no biological of your own, but blood often makes little difference. Yes, you DH should have been more empathetic and tried to understand, but don’t dwell on it. DH might feel “guilty”, might just not understand or believe you “should be over this now”.

Enjoy the love and joy which will come from this new baby.

Oh dear, these kinds of AIBUs are always difficult to answer, because there is usually so much that is not said which might put a different perspective on the matter.

Firstly, I can understand your sadness at not having a child of your own, however you say the reason why is basically "his fault".

Is it possible that he felt guilted by your comment? That could explain why instead of being sympathetic, he became angry?

I'm sorry you're experiencing this pain and sadness.

DancingDuck - what your childless friend said is so sad.
We (mothers and grandmothers), never seem to realise the grief our childless friends carry.
I have 2 childless friends. When we go out as a group, there’s one particular person, who constantly talks about her children and grandchildren . This is getting to the point where we are considering not inviting her to our evenings out.
You are not being unreasonable. Your husband is quite insensitive
