Ok here is the deal. One of my friend is in relationship with white Gal. After texting and skypeing for more than a year, finally they decide to meet with each other. Ok now need some tips for there long lasting relationship. What to except and what not ?

Can't your friend ask for suggestions on sajha himself? If he feels like he needs some tips, he'll seek for them himself. Stop nosing in others' business, you'll live happy, and longer

One of my friends means himself.lol.
If he really has a friend like thqt then I hope he dont have to hold it for him when he needs to take a leak.

skin colour really dose not matter. What matters is character. Please try to know her better and don't think that just because she is white you can take advantage of her for time being and when its time to get married you just marry a women that your parents pick. I have see that with lot of nepali guys.They are a human beings like us and have feelings as well. Just try to know her better and don't forget to ask her age she might be under age and you can be in trouble for that. Ask about her faith if she is a Christain and you a hindu that might mean a huge mess if you actually end up falling in love. Be friends first take one step at a time. But i must say white fellows are much more simple minded and we nepalies are.

Well said Mazzarella.
Do encourage your friend not to make fake promises to the girl. They also have a heart. Do encourage responsibility.
The other thing is she might not be legit. Be careful a lot of deceivers out there these days.
