Man the dynamics of this whole wedding sound like a bit of a mess. You've got the woman attending the wedding of an ex that cheated on her with his coworker. On top of that you then have the guy calling her after the wedding to whine about her taking the attention away from him on his big day, because she was pregnant. By the way, a pregnancy that she never announced on a loud speaker or anything. It really sounds like she was just trying to go with the flow, and do what people asked of her. The folks in the comments section seem to be in agreement that she wasn't in the wrong in this scenario.
