I guess what I am confused about most is why he could be normal for 8 months and then suddenly go into a downward spiral with all PTSD symptoms coming to the forefront. Panic attacks, anxiety, detachment, fear, depression, etc. I never once saw anything like that during our relationship prior to now. Does PTSD come and go? If so, how long do the cycles typically last?

Anything to enlighten me would help.
