Dazed.....
I have been there :( I understand how you feel sweetie. Your husband will wake the heck up one day and realize that he has caused alot of pain to the people he loves and he will hate himself for it. What he is doing to you and your son, he will regret forever once he opens up his eyes, and he will suffer with knowing that forever. It gets ugly. Theres not much you can do now... You are doing the right thing as we speak so continue to do so...i feel alot of anger towards your husband! He needs to wake up already and see what he is doing!! It makes me so mad :( PTSD has nothing to do with cheating, he will tell you that he was "confused" and "needy" BS!! he is being a lil boy.
