Query : my question Is when will my marriage take place? and will it be successful?

Krupa,
According to Vedic astrology my observations are as follows:
1. Sagittarius ascendant and lord Jupiter is placed in the house of disturbance with Venus. Ascendant is occupied by Saturn (retrograde), indicating delay in marriage because Saturn is giving aspect to the house of spouse or we can say is afflicting house of spouse.
2. House of Spouse is occupied by its lord Mercury, Sun and Moon and afflicted by Mars and Saturn. Indications are delay in marriage.
You are passing through Mahadasha of Saturn and Anterdasha of Ketu. Next dasha sequence is Saturn/Venus. Venus in birth chart is placed in the house of disturbance. This can give marriage but possibly some disturbances are possible. But I feel chances or delay in marriage is possible.
Because of free service Navmansha chart and second question is not tested.
