Hello, yes, your charts help us to understand your fear.
In your D9 Navamsha (marriage) chart, your 7th House ruler of marriage is hemmed-in between malefics. This is the case whether you have a Leo lagna or Cancer lagna in this chart.
And in your D1 birth chart, your 7th House ruler is in the 12th from the 7th. This is true not only from Cancer lagna, but also from Chandra lagna and Karakamsha lagna.
Additionally, natural and functional malefic Ketu in the 2nd House of family life afflicts the 7th House ruler, while functional malefic Jupiter strongly afflicts the 7th House by being exactly on its Most Effective Point.
Jupiter also very closely afflicts the 3rd House and 3rd House ruler. The 3rd House signifies courage, initiative, motivation, and enthusiasm.
And functional malefics Jupiter and Saturn ran their mahadashas during your first 27 1/2 years of life.
So again, your fear is very understandable.
However, in July 2016 you enter the 17-year Mercury mahadasha, and Mercury is a functional benefic in your chart, ruling the aforementioned 3rd House.
I trust your fear will not dissuade you as much during this period, as it has in the past.
Propitiations should be done for Rahu, Ketu, Jupiter, and Saturn...

And strengthening measures should be undertaken for the functional benefics...Sun, Moon, Mars, Mercury, and Venus.
Namaste, and thank you for sharing so genuinely.
