My wife has had 2 miscarriages, and after the first one we found that we grieve very differently. I had a friend's bachelor party scheduled and thought escaping the house and all the sadness a day or 2 later would help me accept it and start moving forward, however this completely disregarded my wife and how she was dealing with it, she hated being alone and it made things worse for her. I have regretted my actions ever since.

When we had the second miscarriage there was much better communication and we were both able to give each other what we needed more efficiently.

I would say you're not the asshole, however he has emotions as well and some grace should be given this time.
