hello Sonal
your Lagan has strong venus connection and boy’ lagan has Jupiter connection.
So they have ideological differences about life .
Due to Jupiter and ketu connection….and venus connection in marriage.
There will be ideological differences in marriage.
As per per vedic astrology only 20 points are coming which is low score ( through crossing 50% minimum marks needed.)
This marriage due to age difference also is not recommended , but considering your retro saturn ..which forces you to choose someone very matured as life partner.
You are advised to consult senior astrologers for further questions on marital compatibility.
