Hello equiiaddict: I'm sorry you did not receive a reply to this post. It certainly is deserving of one. Unfortunately, I'm not the best member to be responding to your concerns. Perhaps other members who are more knowledgeable may yet reply.

Are you familiar with California therapist Kati Morton? Kati uploads mental health related videos onto her YouTube channel. I know she has done quite a few on PTSD. If you're not familiar with Kati's videos, I highly recommend them.

Beyond that, hopefully, your partner is seeing a therapist in an effort to deal with his PTSD. Distracting himself in the way he is doing is certainly a worthwhile stop-gap measure. But, at least from my perspective, it's not a solution. Over the long haul, both of you will benefit from him acquiring other strategies to deal with his anger, depression & anxiety. I wish you both great success in your lives...
