I have a question about having sex with my Ex wife. We have been divorced about 2 months now and continue to date and have sex (even the night before the divorce). I was talking to my aunt and told her of this and she said that we could still be married by law in some states. We live in Montana. I wish we wouldn't have gotten divorced (I screwed up) Is there any laws concerning this? Is it possible to have the Divorced Decree Dissolved and reinstate the marriage? Thanks Blue
