I can answer for ts.

Can you check how sure you are she likes you. If it's as real as you say. Then she could be very comfy with online and anxious when meeting in person. After all, you all meet online first.

If she's busy then be understanding. Why the rush? Plenty of time for you in the future.

She may also be very anxious about her looks etc. Rather than say meet up for a date, better to invite her to do what you are doing. For example, do charity or help out. So focus won't be on her and you won't have to face her all time which causes her stress.

Also, don't voice out your dissatisfaction. But maybe disappointment. One is harsh and one is about you're being sad not able to meet her. Which emotion would better when she's the receiving end?

(the above only applies of she's really into you but haven't met you) (if she ain't into you, then move on).

Men need to learn the art of wooing. That, I can easily say, foreigners do it better. Don't learn about their sweet talk. Learn how chill they're and don't only focus on becoming gf bf. Really just enjoy the process of hang out and meet up like meeting up any other friends. When exclusivity comes, then be romantic. You'll nail it.

Good luck, my friend.
