For the OP:

1. Block and Delete her number from your contacts
2. Delete all messages
3. Deactivate your Seeking account for a while or block/Delete her.
4. Multiple visits to some shops (If you are into Asians 42G, No5, Ginza). Try any girl you fancy till you find an attractive girl with good service.
5. Explore the shops, try someone else. Don't stick to one you liked. Just to make sure you don't fall for another one
.
5. In a couple of weeks you will forget about that Girl.

Remember you are just an ATM to her and she is a fantastic liar. It's her job. Get real or you will end up in a very sad place. This is their game, and most of the times we are complete idiots infront of them.
