Your only fault was an optimistic leap into an ill considered marriage with a fractured partner. Lots of people do that. So sad.
Chick, please honestly consider whether he is the right father for your future children. I believe that you thought so, but consider the possibility that he is too messed up to be good parent material. His cold selfishness is interesting and alarming. I did read backward. I do feel so sad for you.
What is your military obligation? Are you going to be deployed as well? Dragging your feet about the D seems to making him more intent. Consider gunning for it with him in a faintly sincere way... In my own bad situation, when I fast forwarded, he backed off. "You are right, Jack Ass, we did not have fun or love each other... I will not keep you from your icky destiny... off you go!!"
Please be creative and do not be afraid of the future. You are still young. It will definately be interesting.
