I told my mom over the phone the other day that my husband moved out. The first thing she said was "does he have a girlfriend? because that's how your dad was treating me when he was fooling around." Well, that sent me into other modes of panic until I realized I had already dealt with that issue, several times. Then she said it was because we hadn't included God in our lives. I know that she meant well, but it wasn't terribly helpful. My dad and stepmom were more understanding, and even though they realize that this is a complicated issue, they still want to pound him to protect me. My stepdaughter is also ready to tear him apart, and she's coming to spend Thanksgiving with me, but I'm going to have to have a long talk with her about the need to show support, not make him feel more guilty.
So I think there's going to be a lot of misunderstanding about PTSD when you share the issue with your family. But we also need our loved ones around us for support, so I think its worth it to share and to help them understand.
