It sounds as though you are doing the right things JAZ; very well done for your efforts. As far as prevention however, there are no guarantees. Both of you being in therapy and honestly trying will certainly reduce the likelihood of problems. However truthfully, it is up to Tee to continue with his healing and you may only be there to support and encourage him. Educate yourself as much as you are able about PTSD, as knowledge is power with this illness. I would suggest reading the information sections upon this forum as a beginning. Continue being supportive of him but do not fall into the trap many other carers have, of allowing their lives to revolve around the sufferer. Do not be overly involved or pushy. Additionally continue to take care of yourself and your daughter. Do not neglect your own needs, as they are every bit as important as his. Take good care.
