There are chances for falling into love before 2012. Marriage proposals might have come and reached upto fixation stage in Sun period.
In his life there would be delays and postponements as common phenomenon.
There are feeble chances for negotiations in the Oct 2019. Marriage would be over by March 2020, particularly after Xmas this year.
In case of failure Marriage would be over by 2020, because of Saturn and Moon conjunction.
Good Luck
