Help please!!

 My hubby and I have grown so distant that we now have separate bedrooms.  I've been in love with this man for 18 years, we have 4 kids together & I'm also raising a step daughter (Who I love as my own.  I've had her for six years now) . We have had a bunch of crappy events happen in a row; my husbands hours got cut at work, then our girl dog Libby died suddenly and then in October I had a miscarriage and he won't even talk to me about any of it and the most I've ever seen him cry was over the dog. He didn't tear up at all when I told him I had lost a child and he refuses to talk to me about it and I can't handle being around him because I don't feel that he understands my pain what the hell do I do???
