Hey Benny,
Your questions aren't stupid at all, they are actually right on point and I am glad that you asked them. I know that I do mention the affair a lot, but I guess it's because it is what brought the DID to light, and I am over it only as much as I can be, if that makes sense. Well, I am not worried about him being around the children. I am not sure why, but he has never been close to the children. He has always been really mean, or cold, even to them, so he pretty much has stayed away from them, where they would always go places with me. They never liked to be around him. Now-a-days, however, he's better and oddly, the sex addicted alter has hibernated. My husband was obsessed with sex, but now it's like, according to him, he only hears voices "coaching" him to look at women sexually. But, I have noticed the change. No more gropping, grabbing, forcing me to have sex, making sexual inuendos, all of that has stopped. Now, as far as watching porn, looking at women sexually, masterbating, fantasizing about other women, he says that he doesn't do that anymore. He gets the "urges" and voices telling him to look at porn and women, but he swears that he doesn't. But, if an alter takes over, would he know if he has looked at porn, matsterbated, etc?
You are absolutely right. I have thought that in the past from a movie that I saw where the man had been sexually abused as a child and didn't want to get close to his children because he was afraid that it could happen. So, he was mean, cold and distant. That could be why my husband has been that way all of these years, or an alter has.
Thanks for bringing this up. I do try not to over react and think like "my goodness, what if one of the alters do something to the kids" because I love my kids so much that I think that would cause me to his the door running

. But, what I do is, try think logically and maturely and since the relationship between my husband and the kids is starting to get better, I keep them with me if I know he has a headache, or I notice a change in him. It's still a chore for him to not disconnect, so he never ask me to leave the kids with him anyway.
Thanks so much for you words and concern, that too makes me feel better to know that people who live with this also think some of the same things I have before.
