He is probably scared and doesn't know what to say. See if you can find a support group for couples dealing with these type of problems.

YA KNOW..ALOT OF PEOPLE WOULD TELL YOU TO STAY POSITIVE AND FOCUS ON THE GOOD IN LIFE....I'M HERE TO TELL YOU TO TRY TO FOCUS ON THE POSITIVE, BUT ALSO EMBRACE THE NEGATIVE. OPEN THE LINES OF COMMUNICATION LIKE NEVER BEFORE. IF YOU HUBBY IS RECEPTIVE, TRY SETTING ASIDE A TIME EACH DAY..MAYBE AFTER DINNER TO SPECIFICALLY TALK ABOUT THE NEGATIVE. STILL TO FACTS ONLY THOUGH. SHARE YOU CONCERNS WITH EACH OTHER AND THE GRIPES THAT YOU HAVE WITH EACH OTHER. IF YOU HOLD EACH OTHERS HANDS WHILE DOING THIS YOU SHOULD BE ABLE TO SHARE THE ENERGY AS WELL AS SPEAK OF IT TO EACH OTHER. PLEASE SET A TIMER SO THE NEGATIVE AND GRIPES DON'T CONTINUE FOR MORE THAN ABOUT 10 MINUTES..SOMEDAYS MAYBE 30 MINUTES. ONCE THAT TIMER RUNS OUT, ITS TIME TO EMBRACE EACH OTHER AND EMBRACE THE NEGATIVE IN EACH OTHER. HUG EACH OTHER AND MAKE THE REST OF THE DAY UPLIFTING AND BE GENEROUS TO EACH OTHER. TIME WILL BE TOUGH, TIMES WILL GET ROUGH...TIMES WILL SUCK BEYOND BELIEF! IF YOU BOTH ARE PREPARED FOR THE BAD, THE GOOD WILL COME SO MUCH EASIER. IF YOU CAN DO THIS, I PROMISE YOU THAT THE POSITIVE WILL FLOW LIKE NEVER BEFORE. SHARE THIS WITH YOUR HUBBY. IF YOU BOTH CAN FALL IN LOVE WITH EACH OTHERS NEGATIVES AND ACCEPT THEM FOR WHAT THEY ARE, YOUR LOVE WITH BE BOUNTIFUL AND BLESSED. HUGS AND WISHING YOU WONDEROUS POSSIBILITES IN LIFE!!!!

My wife went into a shell of denial. After 4 months we live learn and still grow with each other. You need to talk live a loving couple should. Life is too short for everyone, make the best of it. Clear the air on BOTH SIDES. it can work, Im proof.
