Just bear in mind that if it is MLC and PTSD or just PTSD then the normal rules of divorce busting won't necessarily apply. I followed my gut instinct most of the way and luckily it didn't let me down. So all I can say is go with your gut -if you think he needs a loving hug and support then do it. Withdraw when necessary and try and know when to take some flack and when to say "stop". Good luck with it all.
