Thank you all for your input. I know it is really tough to hide this kind of employment from your potential partner, but I am not quite comfortable disclosing it either :/
At present, we both live in different cities due to our employment reasons, enabling me to continue in escort business. I will still be able to do this, even after marriage, since he is always moving around due to his job, and he doesn't mind me living in a different city because of my job.
So I was thinking, if not a career, I can at least continue escorting for a few more years, save up a little, and then give it up for good.
But my only worry is obtaining a mortgage in near future. I would certainly never commit a mortgage fraud by giving fake payslips, that's just stupid.
If I register myself as self-employed, would I be able to claim mortgage then? But it is kinda complicated when you go inside a bank as a couple and enquire about obtaining a mortage loan
I really wish there were some nice ways to manage the situation
