Hi, I'm sorry for your loss but I think he's hurtin just as bad as you are he just doesn't know how to express it. Maybe you should talk to him and let him know how you feel and that you want him there with you. My husband was the same way with my first miscarriage and I talked to him and let him know how I felt. So when I had my second one he was more supportive ...he was experiencing just as much emotional pain as I was. So my suggestion to you is to just talk to him. Open up to him and let him know how you truly feel. Good luck!!
Some men have a hard time expressing how they are feeling/hurting...but this is not an excuse to brush you off and not be the support they need to be.
I had a gorey miscarriage 6 months ago...my husband was terrified, couldn't say a word, just sat there with me while the doctors tried to help us. He was there...that was all that mattered. Maybe this is what your boyfriend needs to understand. And in being there, he's allowing you to also be there for him.
