Financial & now marriage woes.. how do I handle this?

My husband of 6 months got caught in a huge financial mess (he went guarantor for someone years ago, they defaulted, my husband had to pay lots of money just as an "instalment", with future payments to be made, a lot of money). As a loving and supportive wife, I helped him out big time, but in doing so have wiped myself out financially, now seriously struggling to keep up with paying the rent, bills, food, etc, and he has no money. I've been weathering the storm on my own. But for the past week he has been distant to me, doesnt want to talk about it, my questions about the situation and our future have gone unanswered or he has been evasive. Our life has suddenly gone AWOL and we are barely speaking. Im completely miserable, but he doesnt even show he cares by talking to me or even hugging me. What the heck happened? And what do I do? I know his male ego may have taken a nose dive because of the situation, but I did the right thing by helping him out, so why am I now being punished for it?
