Also, I was at a massage place few days earlier and while I was sitting in the waiting room I heard a Thai ML talking to who I reckon was her Aussie boyfriend over the phone. She was calling him "darling", telling him that she's busy on certain days and will be able to see him on other days etc. Her voice sounded very hesitant as if she didn't want him to know she's an ML.

It's sad that she had to hide her job from her boyfriend. She probably liked the guy, and as a bonus is trying to stay on in Australia through him but one problem that I always see in similar situations is that the truth will always reveal itself. The guy will eventually find out, it's only a matter of when it'll happen. That's why if you're looking for an honest, lasting relationship you should start with being honest yourself.
