I've been following your thread all day but didn't have a chance to post until now. When I read that your H invited you to his place for a special birthday dinner with D it made me think three things: (1) The first thing I thought was that H invited you to his place so that he could be sure that you know that the OW and her S are not there. Is this possible? (2) H initiated the invitation and is going to make you dinner. Depending on what he prepares, that could be a lot of work. In the past did he make you dinner on special occasions? Is this consistent with H's past behavior or is this new behavior? (3) Have you been to H's place before? If not, this sounds like a significant step.
