Yes, PTSD can arise anytime after abuse. Many life changes can trigger it or bring it about. For me, many years had passed, thought I had things under control, the next thing I knew (i was at a major life altering time)...........wham. PTSD to the enth degree.......really bad and couldn't reel it in. Now in therapy and on meds, but hopeful to get up and live on one day!
