My husband always put his birth family before me and our children. Always. I tagged along to his family's holiday gatherings for decades, until I finally couldn't face going anymore. So I spent the holidays alone.
After his parents died he began to worship his older sister. She is in charge of our finances now (I'm serious, we have to answer to her as if we are children). No one in his family holds holiday get-togethers anymore and our kids are usually traveling. My husband and I go to dinner on T-giving and Christmas. And that is it. The rest of the time...movies, whatever else, I am alone. Isolated, lonely, and cheated out of a healthy marriage is how I feel.
