Your 7th house indicative of marriage is very weak in the horoscope and the fifth house indicative of children is also very weak. Perhaps if you move to a far off place, your transit horoscope could help.
Venus responsible for marriage in your horoscope is very weak and the marital house the 7th is the weakest in your horoscope. You will have to find your own partner.
Your 7th house has only a meagre strength of 6.5% and that is why you are having problems related to marriage. Perhaps if you change places(more than 1000Kms), you could have a better chance of marriage.
