I have a friend or maybe she's an ex-friend that is pregnant. Our relationship was complicated. Well, here is the problem. She really wanted to have a baby but her husband didn't want a child at the time. When we were on speaking terms she told me that she wasn't taking birth control and that she didn't want her husband to find out. It would seem passive aggressive if I told her husband this but I feel she really betrayed him. I don't know what to do. Any advice?
