- Flowchart produced by provided MWE can be easily fit in one page. So it is not clear, why you like to have last node ("connector) on the next page.
- MWE is unnecessarily complex. By use of
chains and positioning libraries the code can be much shorter, consistent and clear.
- Your MWE is not complete. Missed are connection lines between nodes.
- Arrows in the main branch can be drawn by use of macro
join defined in the chains library.
- In the case, that your flowchart is longer and in question you show only the first part of it, than you need to draw in separate figure the second part of flowchart.
Edit:
- To the first MWE is added the second (dumm) part of flowchart, which was not presented in question
- Deleted is the second MWE

Addendum:
For fun and exercise:
- different style for decision node
- use of
ext.paths.ortho library for feedback loop(s)
