A friend from CA San Jose name Din** went back to Vietnam probably meeting a girl

I have a friend long time ago and we’re still in contact, we met at AMAT. He had dating different girls here in the USA different states. None of them seems to work for him, not sure why, let say he’s at the age where he need to married soon, he’s much older than I am, pretty well educated and own a business, let say it’s a seasonal business. He had family problems as well with his siblings sometime asking me for advice and stuff. I’m not a pro at it but I offer some personal advice don’t know if it help. Anyhow he went back to Vietnam 3 days ago, meeting a girl there and hope that it work out then marriage.
