First let me tell you how very sorry I am for your loss!
Have you two shared your pain? This is a time for extreme patience with each other!
Let him know you love him, in actions if you cannot talk at this time!
I am praying for you both as well as your daughter!
Hugs!

i can't possibly begin to imagine how you feel right now, i just wanted to tell you how very sorry i am.

one thing i do when my boyfriend isn't ready to talk is just tell him i'm available for a discussion whenever he's ready. i'll make some kind of announcement when i walk into the room and he won't talk to me or something. something like, "i feel sad when we're not talking and just wanted to let you know that i'm available for a discussion at any time."

You haven't lost him. Men grieve in a different way. He doesn't know how to say "I love you" or "I'm sorry". It's best for you to talk to him. Don't let the talking lead to raising your voice. Possibly try to get away to somewhere peaceful. He wants your help, he really does. He just doesn't know how to grieve with you..

I see your daughter died in her crib after only being three months old.

As a father, my suggestion is that you allow your husband to handle this loss in his own way. You can see about him getting some counseling.

I know you feel isolated right now. You can get over that. If you can continue to be there for him without holding this isolation against him, then you'll be doing the best thing for your relationship.

I simply can't imagine what the two of you are feeling. I am so sorry. I tried to put myself in his place - impossible really but..you know. I like what jerriean said. Actions. When you walk by him, a soft squeeze on his shoulder. Sitting together, your hand on/in his. Maybe there simply aren't words to say? Actions do speak volumes more. Good luck to you both.
