Didn't you receive a text message when you gave birth?

In fact, others can't help you with this problem, because only you know the reason why he didn't inform you. If there is a gap between you before, I suggest you go to work together, don't make the relationship too tense, and take a step back. If there is no gap between you, you should go all the more. He didn't inform you. Maybe they neglected. Don't embarrass yourself. It's best to go.
