If you are once married, your marriage has taken place. As per Astrology you are a married man. Going in for a second marriage is nothing new as far as marriage is concerned. The reason why you are led to a second one is because you were incapable of keeping one possibly due to incompatibility with the spouse which you should have checked before marriage. Astrology can only see marriage as the first time it happens which has already happened. Wayside astrologers might predict you will have second/third marriages for their own livelihood.

Generally your horoscope is a weak one. Your 1st, 3rd, 4th, 9th and 12th houses are very weak. Marital house has a minimal strength. A second marriage is not going to bring you any more happiness. Your financial condition will improve in due course since your 2nd and 11th house which represents finances are not that weak and it only is undergoing some fluctuations.
