That's cool you tried it. I've done prolonged fast travel before, which is overrated. But staying in one spot for 1-3 months is something I think could be underrated and I want to try.
One trick I use sometimes is to imagine that I'm abroad even though I'm in my normal city. It makes things more interesting and gives me more energy for interactions.
The short and ethnic thing I could understand being frustrating. I'm basically 6' and white and pretty good looking. But even so, it's not the end all. It just opens the door. I don't get with the "cool" types of girls because I don't follow pop culture and play those games. Those types of girls you don't even want. It's tough though. Best way to meet girls is meetup-type stuff like a local running group, local language meetup, etc. Actually care about the activity and befriend the guys, etc. Then the benefits with girls come in a few months (take it slow and don't be the creepy/loser guy just there for girls). ex. I started going to the language meetup, and going hard in the languages and being kind of silly and fun. Now 2 years in, all the regulars know me and I have cred there. If I ever take a girl there, she knows I'm cool. Or new girls there know that I'm cool from the social proof.
If I didn't have a great family that I want to see monthly, I would definitely consider the moving overseas thing.
Basically you just focus on YOUR PATH and believe in what you spend YOUR TIME on. I think people get magnetized towards people with a "purpose" who can spread life energy instead of trying to take energy(this girl should give me love, this guy should give me respect or validation, etc).
