To all the learned gurus here:
One of my cousins is 29 years old and he is still not married.  His birth details are as follows:
Date of Birth:  June 20, 1980.
Time of Birth:  5:35 a.m.
Place of Birth:  Coimbatore - 11n0, 76e58 (Tamil Nadu, India)  
He is the only son and his mother seems to be interfering a lot with his decisions.  The boy is terribly depressed now.
Could the gurus tell us when he is supposed to get married and if any remedy should be performed ?

Sorry if I am being a nuisance, but if the respected gurus require more information, I am willing to provide it.  The boy already escaped a road-side accident last year.  Since 2003, they have been having a lot of family problems particularly from close relatives.  Somebody said that he is manglik.  We would like to know if that is true too.  Thanks in advance for any help that you can provide us.  Please note that the family is really depressed now.

Moon sign is Leo. Moon is along with weak Saturn ( MK), Mars (PiK)  and Jupiter (PK). Here saturn is 7th lord and is weak in Leo.

Its understandable that mother is blocker for marriage. But she is not thinking bad about son. Its that she is kind of old thinking, conservative and want a perfect daughter in law for the family (possibly possesive too).
Rahu is DK here. Currently running period of Rahu. current AD is Saturn so it is slow period and not expected to give any great results.

there is marriage chance when jupiter moves to Aquarius (7th from Moon)in dec 2009. He will get proposal during Rahu-Merc period from Feb 2010.
Care shud be taken that horo is matched and also good verification of girls character and attitude is need to be taken care ( As Rahu is DK possibility of getting wrong person who can spoil family life. )

Dont worry too much. Pray Daily "Ohm sharavana bhavaya namaha".
Also pray Lord Durga. Visit durga temple on fridays.

Thank you very much astro_scholr ji.  As you said, the mother is highly possessive.  In the beginning she did not want her son to get married at all but later she obliged.  She already spoilt one prospect which the boy liked two years ago.

I would appreciate if other learned gurus here are able to give more input.

I would also like to know if there is any free match making software.
Once again, thanks for your cooperation.

may be there communication problem b/w the mother and son which needs to be resolved. since saturn is 7th lord its better to get married after age 30. she might have visited some astrologer and got opinion that Rahu mahadasa is bad and marriage needs to be delayed.
