i could understand with losing an already born child, but a miscarriage means losing a child that is yet to be born, yes it's a tragedy but leaving your companion in their weakest moment because you can't deal with it in my eyes marks you as a waist of air and a person i'll avoid associating with
and i'm talking about the man leaving the woman in this particular case, not about losing an already born child or any other variant
with that i can understand that the mental trauma of an event like that can lead to the ending of the relationship
just my opinion
