Everything I say is wrong

I AM A WIFE OF 4 YRS TO A MAN WHOM HAS EVERY SYMPTOM OF ADHD.  WHEN WE MET I COULDN'T ASK FOR A BETTER PERSON OR FRIEND TO MY 3 KIDS FROM A PREVIOUS MARRIAGE.  I COULDN'T ASK FOR MORE.  I AM ALSO A MOTHER OF A CHILD WHO HAS ADHD. WHEN WE GOT MARRIED THE FIRST COUPLE OF YRS WERE GREAT. THEN AFTER THAT EVERYTHING I THOUGHT WE WORKED FOR HAS JUST FALLING DOWN HILL. OUR ARGUEMENTS ARE ALOT MORE FREQUENT. WHEN I TRY TO DISCUSS THINGS WITH HIM HE GETS MAD AND TELLS ME ALL I WANT TO DO IS MAKE HIM MAD OR FUSSING FOR NO REASON. I WORK A FULL TIME JOB 5 DAYS A WEEK AND HAVE ALL MY KIDS ACTIVE IN SPORTS.  I AM CONSTANTLY ON THE GO AND YET I STILL HAVE TO DO EVERYTHING AT HOME. WHEN I TELL HIM I NEED HIS HELP HE TELLS ME I WOULD HAVE TO DO IT EVEN IF HE WASN'T HERE. IF I PUSH THE ISSUE HE HOLLARS AT ME AND THREATENS TO LEAVE ME AND TELLS ME HE WISHES HE NEVER MARRIED ME. IT SEEMS AS LONG AS I DONT SAY ANYTHING EVERYTHING IS FINE BUT IF I DO THEM I AM IN THE WRONG. WE NEVER SPEND NO TIME TOGETHER B/C WHEN MY KIDS ARE GONE TO THEIR DADS EVERY OTHER WEEKEND HE THINKS WE HAVE TO HAVE A HOUSE FULL OF PEOPLE. I TRY TO GET HIM TO GO OUT TO EAT WITH ME ALONE OR JUST GO AWAY FOR A COUPLE OF DAYS HE NEVERS FALLS THREW WITH IT.  I COULD GO ALL DAY WITH THE THINGS THAT HE AND I GO THREW BUT MY MAIN CONCERN HERE IS I LOVE HIM AND I DON'T WON'T TO LOOSE THAT LOVE FOR HIM. HE LOST HIS MOM AS A CHILD AND HE HAS HAD A HARD LIFE GROWING UP. EVERYBODY HE COMES IN CONTACT WITH LEAVES HIM OR HE PUSHES THEM AWAY. I KEEP TELLING HIM I'M NOT GOING ANYWHERE SO HE NEEDS TO STOP TRYING.  IN ALL HONESTY THIS MARRIAGE HAS BEEN NOTHING BUT COMPLETE TURMOIL. I TOLD HIM HE LOVES TO KEEP SOMETHING ALWAYS GOING B/W US. IT SEEM WHEN EVERYTHING IS GOING GOOD HE HAS TO THROW SOMETHING IN THERE TO MIX IT ALL UP. HE SAYS HE LIKES TO KEEP ME WONDERING. PLEASE IF YOU CAN HELP ME WITH ANY ADVICE I WOULD LOVE TO HEAR IT. I WANT MY MARRIAGE AND THE FAMILY WE HAVE TOGETHER BUT MY PATIENCE IS RUNNING THIN.
