I kind of get what Golem is saying. You don't always have to go somewhere to be comfortable or see something aesthetically pleasing. The opposite can be very enriching and meaningful experiences, which is what you'll get in Kathmandu. A trip there might very well change the OP's life. It won't exactly be comfortable or romantic though. Pokhara is really a pain to get to and takes a day of traveling as it is, and for getting back to your flight to Kathmandu, you need at least one extra day leeway.

If the OP is interested in going hiking in Nepal, you can hire a female guide. I can maybe give you recommendations if you need. I think it's pretty safe, although if you dig there are a few horror stories. Most dangerous part -- in my opinion -- is the transportation which will make HK taxi drivers seem utterly civilized!
