VHD just don't go with the arranged marriage if you don't want...youre an out atheist so it doesn't matter :/
Unless of course the girl is very attractive, and hence the less resistance this time round

Nah, the girl first time round was way more attractive but I was bit more passionate about
my life back then. Now, I know marriage is just a small step. Just because I am an atheist does not mean I cease to have expectations and relationships with my family. Sure, I could refuse but in the end its not worth it. I don't believe in love or marriage, so in turn I see it as small contribution to my life.
VHD are you in UK/US or are you in some Islamic country? If you're going ahead with the arranged marriage and you don't like the girl, then know that you are also ruining the girls life. I was in the same position as you and my parents wanted me to do an arranged marriage but I stood up for myself. If you can't act like an adult, then you're not even ready for marriage anyway.
You need to stand up for yourself! Don't get married to someone whom you don't like. Life is only once!
I dunno how to take your post dude, I gather you think I cannot act like an adult and cannot stand up for myself. I been through it all, I have gone the rebellious route, "
stood up for myself" and in the end learned it makes no fucking difference. There are more important things to me than marriage, and I am not prepared to strain relationships for something I care so little for ever again. My Mom > East vs West cultural collision.
Why do you assume I am ruining the girls life? Fortunately my family has a tradition for allowing around about 1.5 to 2 years before actual marriage. That is plenty of time for me to let her know about the elephant in the room. Then its up to her and I wont be at any blame if it gets called off.
