(A) How do I add this woman on a form of social media with an accompanying note stating how I found her profile without knowing her name?
RED FLAG !!! - Men CANNOT and SHOULD NOT do this for a multitude of reasons !!!
(B) How do I convince this woman, the Goddess sent to me directly from Shanghai, to leave her lovely, loyal boyfriend, and get with an Arab man who cannot satisfy her in anyway, shape or form?
In a way, I pity you guys these days. It's not easy finding love. Back in the day your Uncle CK was blessed with good looks and charm which opened a lot of doors. Without internet you had to step up your conversation game. But the rules of yesteryear are gone out the window, and what used to be tolerated may wind up getting you arrested these days. A lot of what I used to get away with wont fly in 2019.
Brother - It is simply NOT socially acceptable for you to approach her online or using work channels. She'll go away feeling threatened or worse 'scared'. She'll wonder about what your true intentions are, and/or create anxiety about when you might return. Without you being there to answer the questions directly, she'll fill in the gaps about what you were trying to do and if she feels in the last bit uncomfortable about what you're doing, nek minnit your HR department is handing you your marching orders.
Accept these facts as truth : In your circumstance, you're in a bad spot with few viable choices available.
There is a very, very, very slim window of hope for you ... If this is gonna happen at all, it MUST be organic. You can't force it. And you need to be self-aware so you drop it like a hot potato at the first sign off resistance. Fuck it up, and you're THAT GUY among her whole office and circle of friends.
(a) This is marathon, not a race - It starts with crossing paths externally in daily life
(ie: food courts/shops for lunches, niteclubs you both happen to attend, a shared gym, etc, etc). Then you can act dumb and the chat can be about "Where do I know you from ? Ahh yes, you're from that bank ! It's good to see you again." ... BAM, door is open. After that
(and only after that), you can go back to work and try to facilitate a second work related encounter. Hopefully, she'll remember you. If she does, the next part of the plan is ...
(b) Go old school. Be polite and write her a small note ! ..... Include your contacts. Don't ask for hers.
The note should have a certain tone about it that says
"Hey there, I don't want to intrude and hit you up for your deets at work, so I figured I'd give you mine. I find you intriguing and if you're ever free for lunch, or if you wanna hit me up in my DM's, I think we could have some laughs together. If not, that's perfectly OK too. All the best - Wahesh".
Finally - It's probably for the best that you simply let her go. I could write 5000 words on the topic but in short, this idea that you'll somehow be complete when you meet the right girl is Hollywood Horseshit. For decades men have been sold the idea that bold displays of affection will sweep a girl of their feet and everybody will live happily ever after. This is WRONG. Fucking movies and TV have been lying to us for too long.
The reverse is actually true. Work on yourself. Make yourself happy. Get your shit together. Create a lifestyle that involves you investing in your own happiness without the need for a woman. Before you know it, they'll start to notice YOU as a capable type who always smiles and seems to have the world by the balls.
