Stop sending money.
I know a few girls on Soi 6 who are receiving monthly payments from several guys abroad, they're making up to 100000 baht per month.
You got to switch off now, take the loss, it's over.
I worked with an American guy, from Louisiana (strange guy, not all there) in Angola, our rotation was 28 days, he was useless, sulking, sobbing, worried about his promiscuous soi 6 lady for his entire hitch.
The rig can't survive having a man down all hitch.
