Once my wife started giving birth I left the room.
Why did you leave the room?
I was afraid something was going wrong and I couldn't stand the blood.
You should have been in the room to support your wife. She needs your support while giving birth and you should have given it to her.
I'm not a fan of blood.
While it would be difficult, you could have just turned away and remained in the room. Your wife will need you once this process is all over to be there for her.
