<human>: Could you distill the essence of the text into 1-3 sentences?

I'll try to keep this brief since I know I hate reading long AskReddits (not main account, obviously). 

Wife and I have been married for about a year. I spent most of our relationship putting her through school working in Iraq and Afghanistan, about 3 years prior).  

Since we got married, she stopped putting out (sex every couple of months is not putting out to me), put on about 60lbs (no, not making that up, was 180 when I met her, just under 240 now).  She recently got promoted at work and started working crazy hours.  

I am using my GI Bill and going to school full time, I am also a disabled vet (not trying to curry pity, just that they pay me) so I don't have to work.  I have also put on about 20-25lbs (fluctuates) and am not all that attracted to her.  

Major issues recently are that she used to do most things around the house, because she had time to and because she had no choice, I was gone.  Now she doesn't have time, and she has a choice, so I am trying to help.  I suck at this.  I can kill people from great distances, but I'm not great at remembering to take out the trash or clean the litter box, make dinner, etc.  

She yells at me for this, I feel emasculated by that and naturally yell right back.  Nothing is solved, it's affecting my schoolwork and I don't see a light at the end of the tunnel.
<bot>: Wife and I have a shitty relationship right now.  We are both unhappy.  I don't know how it will get better or how to fix it.  Should we get divorced?
