Thank you for writing about your experiences in such detail and with much honesty. I wouldn't be quick to close the door with Bee. He seems to be genuinely in need of financial assistance. If I remember correctly, when he first met you, he didn't talk about money at all and he seemed like he wanted to know whether there could be chemistry between the two of you for a relationship.
It takes time to get to know a person. I encourage you to keep in touch with him when you are back at home. If you are able to maintain meaningful online conversations with him, that shows there is some connection in your relationship. If you want to, you might consider sending him a small sum of money every month to help him slowly clear his debt. However, you should be the one deciding how much to give and it is based on how much you are prepared to give and not how much he asks for.
I have known my regular guy for 9 years now and it started back in 2016. I subsequently met him every time I visited Bangkok.
In 2019, he was disillusioned with the life working in a bar so he asked me if I could support him monthly if he went back to Vietnam. It was a reasonable sum and I could afford it so I said yes. It was not his only source of income. He worked and my money merely supplemented his earnings as he provided for his parents. But Covid hit and things were bad. The job situation in Vietnam didn't recover after Covid so he came back to Bangkok to work in 2022.
I got reunited with him physically and have been meeting him for the past few years. He's done well enough that I have stopped sending him money every month. Of course, I tend to give him quite a bit more than a regular customer when I meet him in Bangkok!
Our long distance relationship consists of chatting about mundane things such as "what did you eat for dinner?" or "how's the weather?" but we also ask about each other's health and share about our individual life.
