O my. My heart goes out to you. One thing I don't want you to do is to excuse this ABUSE...are you listening...it is ABUSE....because he has PTSD. It is his issue to deal with and drinking is certainly not the solution. You did not cause it and you cannot cure it. I hope you get in touch with a shelter or do whatever you need to do to get out and stay safe!!!
Hugs and Blessings! Keep posting, you are not alone!
