@Kingsandqueenz you are fantasising, why?
Chelsy could not have married Harry, permission would not have been granted,
despite their friendship groups overlapping, including Cressida, the aristocracy
being famously intertwined.
Harry would not have been allowed to marry Chelsy for obvious reasons already stated here with more besides.
Their relationship had run its course, she was fed up with him, it was going
nowhere.
Chelsy has moved on OP, why can’t you.
