Dibya Raj, Nobody gives better suggestion than me, and I am giving you my million dollar suggestion. Don't marry, at least not until you are 32-35. 29 is not an age to get married. It's your loneliness that is kicking you below your belly and that is exactly what makes a man vulnerable. That is exactly what makes you want to get married. The more you think about it, the more you get into this pile of dung. So, the best thing for a time being is, listen to Chiple Dhunga ( I liked what he said). If you find a girl that you can talk for an hour without getting bored, marry her. It doesn't matter which nationality she is. If you don't find a girl right now, then wait, finish your Phd. Until then, make new friends, meet new people, socialize, engage yourself on other stuffs so you don't get lonely. Visit brothels, if they have it, else, gratify yourself. Whichever way you can release it, do it. When you are done with school, You can go back to Nepal, get married with a homely girl. There are bunch of half naked Nepali party girls in PartyNepal.com. Let me assure you, most of them are not taken. The pond is big and there are plenty of fishes.
