How old r u? And r u married? If u r what does your spouse have to say about it? And if you are not married why not? Marriage may help emptiness in your life if u find the right person regardless of where you live here or Nepal .
I go back every year and enjoy every second of my time there but I won't be able to settle back there.
I do think if you are going to go back you should make sure you have a way to come back if you want to. Knowing that there is that option for you even if you don't come back will make things easier for u.
