Betterhelp was already mentioned, but it needs a subscription. The center you want to try is good. For another option you could try https://www.instantcounselling.com/
It’s basically that: instant councelling. Almost 24/7 you can reach someone professional instantly. Pay as much as you use.
The only disadvantage is that you need to call to the UK by phone. So from Taiwan it might make more sense to use Skype out or other similar services.
Apart from that: it’s great that you try to understand what she wants and needs. Maybe if you give her the feeling that you really care what she wants and needs and why, that could help make her feel more positive about the relationship. I mean only listening, not starting to discuss and reason. Just listen. Acknowledge her feelings, needs, wishes.
