Howling:The Doctors family

I just thought about something regarding the doctors family.

1-When he left gallifrey, what happened to them and did he even think about how it would affect them? 2-Why out of all his family was Susan the only person he took with him. 3-When the doctor returned to gallifrey in later stories, especially when he became president TWICE, why did we not see his family then either? 4-How does the doctor having relationships with other women (i.e. river song as his wife, queen liz the first as wife, rose as his unrequited lover, all his female companions he has kissed and romana-a fellow time lord), fit in with the fact he had a wife and had at least one child and at least one grandchild(susan) to her. Did he never think how this would affect her?--Coop3 ☎  22:51, July 3, 2013 (UTC)
