Lifeisahighway bro, You better start thinking about it seriously. I mean, this is the real Nepali community and by that i mean, SAJHA. Timle yaha jati ra jasto positive / negative response payo testai reponse pauchha jindagi bhari. If u can reply or ignore all of these responses and move forward with your cousin as your wife, then go ahead.. and, u know very well that you will have the toughest social life b'coz its like betraying your family and relatives (both of you)..

Radiohead, thats really funny yet true.. Seriously, life bro, you can try this.. lol.

Hope you will make a better choice.Good luck.
