Your concern shows your love caj. All you can do is wait and see. he is going through a traumatic experience just now, and he will take a while to get over it. Your love will help more than anything. You are his safe refuge, he may act in strange ways, (when I first came back from Northern Ireland my wife and I were walking down the street when a car backfired, I dived over a hedge into someones front garden reaching for my gun, which of course I did not have with me, my wife justy walked on until I caught up with her feeling a bit sheepish and she never said a word...Niether did the owner of the garden, she knew where we had been.) So be prepared and give him time to adjust and all will be fine, try not to argue, if you can, his love for you will not change.
