Usually you restate your thesis in the conclusion, so I'd say B.
Dear friend.
I am writing this letter because I woke up missing you so much and I couldn't help but tell you how important you are, not only to me, but to everyone who loves you here in Nepal.
For this reason, I believe it is time for you to return to your land and the people who love you. You've been away for so long, I believe you're missing it too and want to see and live with your people.
Your family is growing, your country is growing and it would be a shame you weren't here to witness it all and live in the culture that is truly yours.
However, I don't want to pressure you into making this decision. I know that everything happens at the right time and at the right and appropriate time you will decide to go home. I hope this happens soon, as I really wanted to see you.
With love
M.S.
