Please clarify whether you got any alliance reached upto a final stage and missed. It is in the period 2011-2014. Please take care of proper check of compatibility of charts before marriage. Saturn, who is in the star of Moon, gives you delay. Saturn is aspecting 7th house. Don’t expect love marriage. There are feeble chances only.
The groom comes from your known family in the local area where you live.
After 19-12-2018, the alliances will come and marriage will take place by May 2019, in case of failure it will not cross 2019.
Your marriage is likely to take place before 2022. Your 7th house lord Venus is very weak. The only pragmatic remedy is to wait till you get a good match. You cannot change your potency of your horoscope by shortcut remedies. Pray to God and that is the best remedy.
