There are a lot of things between "with husband" and "alone", and a good many more that are not exactly between but clustered in the same general vicinity. There's couples counseling for infertility (seriously, folks, this can be a real emotional blow for both people, and you should look into this). There's going to visit, both of you, and explicitly making it ok for both of you to take time alone, together, whatever, away from the others and their babies and the painful and complicated emotions they raise. There's both of you staying home and doing something special together that both acknowledges your pain and tries to imagine a future beyond it. There's letting the husband go and staying home ... and spending time with friends, building your local support system. There's, I dunno, acknowledging that all of this is harder and more fraught with some kind of global pandemic going on where the new babies can't be effectively protected yet.

I don't closely follow any of the advice responders, but yeah, I'm sure not impressed with the quality of this answer, even if it gets things vaguely right. There's absolutely no depth to the answer, nothing exploring the myriad ways that they could navigate this. This feels like it was written as a "I have to write one more response to meet my quota before the deadline" and were I the LW, I would be pretty put off by it.
