Most Helpful Girl
Based on his demeanor, I think he is grieving a loss just like you. Furthermore, what makes this situation even more stressful is the fact that he has gone through this BEFORE. He is burying himself in his work and keeping busy so he doesn't "have to feel anything" and it's easier to cope. In addition, I attribute this to the fact that he wasn't there for you when you experienced complications.
I am not condoning his behavior in any way because you both needed each other during this period of time. This experience was just as stressful, emotional and physically draining on you, perhaps even more so since you were pregnant. However, men are effected by these things too and he probably has a lot of guilt that he has had to deal with this choice again. He is probably feeling dead inside.
This is my perspective. I hope you are feeling better and both of you can move forward in a healthy way.0
