I am a mess over separation...husband is done. Advice? Advice from men would help too!

Let me make a long story short. I have been with my husband for 13 years(married 8). We have 3 children. I am very outspoken, he is not. He does not share his feelings AT ALL! He didnt start out this way...it just got worse as we got older. The last year has been bad. We went through different therapists but none of them were too helpful. They did agree when I told them I thought a spearation would be good for us(maybe 2 weeks).Well, my husband would ver do it. In July, we were trying to make things work. He told our therapist he was in for trying 100%! Even more than me. We were trying but him ignoring me at home got bad and I got really mad. I told him to go and he finally did. After a week of barely talking, I called him to see what we should do to move forward and he said he is done. I was heart broken, I still am. For weeks now, he keeps telling me he is not angry or anything but he is done. He says he wants me to be happy but does not feel at all that he wants to try again. ever. Im so upset...I'd rather him hate me then say he cares but doesn want to try one more time...any advice for me??
