I don't want to marry my cousin

Rose_petal, just a word of wisdom. give it a second thought. sometimes, what parents think is because of experience and sight. Feelings do develop between husband and wife over time. I have seen many successful marriages like this.
In fact, I have seen love marriages failing big time these days.

For any new relationship, patience is required to develop understanding....some have 3 years of mangnee, daily meetings, talk over phone.....and end up in divorce just in 4-8 months after marriage.

I am not hurting you. You are free to decide. Just a word of wisdom from an elder.

Real world is different than the fantasy world of feelings.....

Also, go to an online site where match making is available using date of birth....there are Western and Indian Kundli making sites on internet (search in google, they are free. it takes a minute to check)....they will give results whether your stars match or not according to birth chart. You will have to put date, place of birth, location, etc. It has importance. Reject the rishta...if the results are "mismatch" or "no match". Trust me, moon, sun, earth, all have relationship with our lives....energies.. It is one aspect of our married lives.... It will show u score...like -500 or +500.....better if 1000+.....its a science well studied.....
