Query : bad 1st marriage,any chances of second marriage when??

Megha,
According to Vedic astrology my observations are as follows:
Since ascendant is less than 0 degree, so accuracy of time (birth time) is very important, because variation of few minutes can give different ascendant, and promises of horoscope will be different.
1. Scorpio ascendant (just 0 degree and 23 min.) and lord Mars is placed in the house of profession, with the lord of spouse and gains and achievements. Ascendant is occupied by Jupiter.
2. Spouse hour lord is eleventh house lord Mercury, indicates that multiple marriage.
3. Since Mahadasha lord Mercury is placed with the lord of spouse – Venus. But Mercury represents eighth house (house of miseries), indicates that disturbance in married life, but multiple marriage.
You can have marriage within this Mahadasha. Since I am doubtful about your birth time, so can not give period of marriage.
