Your marriage sounds a lot like mine before we went to Retrouvaille. I felt like I was just everybody's servant, and no one cared to even notice me unless I failed to do something for them. For us, the weekend was a miracle cure. Our problem was in communication. I buried all my hostilities or muttered them under my breath, occasionally I exploded in anger, but it didn't win me any friends or change anyone. You should look into Retrouvaille, http://www.helpourmarriage.org.; it could be just what you need.
Where will you be visiting in Florida? I live in Tampa.
